sizes of pathnames produced by expansion of tilde (home-directory)
prefixes by replacing S_pathname, S_pathname_impl, and S_homedir
with S_malloc_pathname, which always mallocs space for the result.
one thread-safety issue involved the use of static strings for expanded
pathnames and affected various file-system operations. the other
affected the file open routines and involved use of the incoming
pathname while deactivated. the incoming pathname is sometimes if not
always a pointer into a Scheme bytevector, which can be overwritten if a
collection occurs while the thread is deactivated. the size limitation
corresponded to the use of the static strings, which were limited to
PATH_MAX bytes. (PATH_MAX typically isn't actually the maximum path
length in contemporary operating systems.) eliminated similar issues
for wide pathnames under Windows by adding S_malloc_wide_pathname.
consumers of the old routines have been modified to use the new
routines and to free the result strings. the various file operations
now consistently treat a pathname with an unresolvable home directory
as a pathname that happens to start with a tilde. eliminated unused
foreign-symbol binding of "(cs)pathname" to S_pathname.
io.c, externs.h, new_io.c, prim5.c, scheme.c, prim.c
- various places where a call to close or gzclose was retried when
the close operation was interrupted no longer do so, since this can
cause problems when another thread has reallocated the same file
descriptor.
new_io.c
- now using vcvarsall type x86_amd64 rather than amd64 when the
former appears to supported and the latter does not, as is the
case with VS Express 2015.
c/Mf-a6nt, c/Mf-ta6nt
- commented out one of the thread mats that consistently causes
indefinite delays under Windows and OpenBSD due to starvation.
thread.ms
- increased wait time for a couple of subprocess responses
6.ms
- added call to collector to close files opened during iconv mats
specifically for when mats are run under Windows with no iconv dll.
io.ms
original commit: ad44924307c576eb2fc92e7958afe8b615a7f48b
the zlib header files, since zlib's configure script can modify the
header files. removed ZlibInclude variable, which no longer serves
a purpose.
c/Mf-*, c/Makefile.*nt
- removed unnecessary datestamp.c target
c/Mf.*nt
original commit: d081c5b19a185597443f47101caa35b8c12084c7
- added a cast to eliminate warnings in c/number.c
- fixed bug in Windows version of directory-separator-predicate in s/6.ss when path-* procedures are passed a path that is not a string.
- fixed bug in s/cp0.ss on Windows with $foreign-wchar?.
- fixed spelling of non-existent

reflect the Version 9.3.1 change from sstats structures to sstats
records, with sstats times represented as time objects and sstats
bytes and counts represented as exact integers; also updated the
sstats-difference description to reflect that it no longer coerces
negative differences to zero. added a corresponding release note.

original commit: cd93f130c2a911d67bc19b75da0f205d50b8f6ff
This changes the configure script from unconditionally assigning CPPFLAGS,
CFLAGS, and LDFLAGS to the empty string, to only assigning them to the empty
string if they are unset.

files that no longer exist, which was getting in the way of creating links
for files that do exist. Also updated the build batch file for Windows to
compile the nanopass framework separately before building the rest of the
scheme compiler and libraries.
s/Mf-{a6,i3,ta6,ti3}nt, s/bldnt.bat,

original commit: 4339b856d85de4c949ef7c4e66ec679512809a58
* Mark the files as HTML5 rather than HTML4.
* Use target attributes rather than onclick events to open links in specific windows.
* Add a missing table row element.
* Replace the deprecated name attribute with an id attribute (and replace the anchors with spans).
* Replace the deprecated valign attribute with a style attribute.

machines with libraries and header files installed in alternate locations on
unix-like operating systems.
configure, workarea, checkin,
c/Mf-base, c/Mf-*
Added support for building from a directory that is not a git checkout in order
to support creating release source packages.
configure
original commit: 41d94b0793997e3b90c10d6d28aaa4e2d43857cc
dated back to Version 8.4 or before and to combine the three performance
subsections directly related to the new compiler back-end, since the
changes all occurred between publicly available releases.
original commit: 65df1d1f7c37f5b5a93cd7e5b475dda9dbafe03c
and configure creates a config.h that sets the default scheme heap
path and scheme-script name based on the actual configuration.
configure, newrelease, workarea, checkin,
c/Mf-base, scheme.c, main.c,
Mf-install.in
- renamed the installed example directory from lib to examples.
Mf-install.in,
scheme.1.in
- added force option to gzip during man page install to prevent gzip from
asking for permission to overwrite existing man page files.
Mf-install.in
- removed ~/lib/csv%v/%m from the default scheme heap path on unix-like
systems. documented inclusion of %x\..\..\boot\%m in the Windows
default scheme heap path.
main.c,
use.stex
- added new configuration options: --installbin, --installlib,
--installschemename, --installpetitename, and --installscriptname.
configure
- updated the example library link to the nanopass framework.
CONTRIBUTING.md
- now cleaning up petite.1 and scheme.1 left behind by make install
Makefile-workarea.in, checkin
- now removing workarea after cleaning csug and release_notes so
Mf-stex (included from csug/Makefile and release_notes/Makefile)
doesn't complain trying to determine the machine type.
Makefile.in
- added installsh support for --ifdiff so the csug make file can use it
for the install target.
installsh,
csug/Makefile
- added instructions for building (cross-compiling) a boot file for
a supported machine type for which a boot file is not built by default.
BUILDING

line from the wpo file (if it has one) to the object file.
compile.ss,
7.ms
- stex is now a submodule. csug/Makefile and release_notes/Makefile
set and use the required Scheme and STEXLIB variables accordingly.
they default the machine type to a6le, but this can be overridden
and is by the generated top-level Makefile. the generated top-level
Makefile now has a new docs target that runs make in both csug and
release_notes, and an updated distclean target that cleans the same.
the annoying csug Makefile .fig.pdf rule redefinition is now gone.
copyright.stex and csug.stex now list May 2016 as the revision month
and date; this will have to be updated for future releases.
configure, makefiles/Makefile.in,
csug/Makefile, copyright.stex, csug.stex,
release_notes/Makefile
- rebuilt the boot files
