original commit: c5b6fe968f890bbef3488d570756cbe8da211326
Check both the beginning file pointer (bfp) and end file pointer (efp)
of the source location associated with a profile counter when updating
its count.
Assuming that each expression has a unique bfp with respect to profiling
seems to give accurate execution counts for s-expression-based source
locations as in Scheme, but causes problems when targeting other kinds
of syntax. For instance, a C-style function call, referencing the called
function by name, such as "fn(arg)", can logically have profile counters
associated with 1) the function name reference ("fn") and 2) the entire
function call expression ("fn(arg)"), both of which begin at the same
source location. Only the bfp is checked when updating profile counters,
so the two source locations are conflated, and only one counter is
incremented, which gives inaccurate execution counts for both locations;
approximately twice as many for one, and zero for the other.

Change the foreign procedure definitions to use the more portable int
rather than integer-32. Switch to a custom port
[make-custom-binary-input/output-port] rather than a generic port
[make-input/output-port], which resulted in deleting quite a bit of
code. Fix various compiler warnings in the C code, and along the way,
fix a signedness bug in c_write that could have resulted in not writing
the full buffer (but reporting that it did) in the case of errors from
write.

allocating the thread context fails from Sactivate_thread. before
this change, the error was raised on the main thread, which resulted
in strange behavior at best. also added who argument to
S_create_thread_object to allow it to report either Sactivate_thread

original commit: 0a6a1e14e7ecb9e39fa7a10a8584ed2fec24cbf4
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.

indefinite delays under Windows and OpenBSD due to starvation.

specifically for when mats are run under Windows with no iconv dll.

records, with sstats times represented as time objects and sstats
bytes and counts represented as exact integers; also updated the

negative differences to zero. added a corresponding release note.

- 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,

- added new configuration options: --installbin, --installlib,

- 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.

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.

obviated scale_float in the process.
number.c,
ieee.ms
- fixed 0eNNNN for large NNNN to produce 0.0 rather than infinity
strnum.ss,
5_3.ms
- the reader now raises an exception with condition type implementation
restriction (among the other usual lexical condition types), and
string->number now raises #f, for #e<m>@<a>, where <m> and <a> are
nonzero integers, since Chez Scheme can't represent polar numbers other
than 0@<a> and <m>@0 exactly. <m>@<a> still produces an inexact result,
i.e., we're still extending the set of inexact numeric constants beyond
what R6RS dictates. doing this required a rework of $str->num, which
turned into a fairly extensive rewrite that fixed up a few other minor
issues (like r6rs:string->number improperly allowing 1/2e10) and
eliminated the need for consumers to call $str->num twice in cases
where it actually produces a number. added some related new tests,
including several found lacking by profiling. added a couple of
checks to number->string whose absence was causing argument errors to
be reported by other routines.
strnum.ss, exceptions.ss, read.ss
