Replace repetitive C code in "gc.c" and "vfasl.c" with an
implementation using a little "Parenthe-C" language, which is a
somewhat declarative description of object tracing. From that
descrition, we generate different kinds of tracing functions, such as
the copy function or the sweep function.
The little language is still bascially C, just with parentheses and
parameterization that is much better than trying to use the C
preprocessor. (The "mkgc.ss" file includes the compiler from
Parenthe-C to C.)
Besides replacing existing code, we also generate a new traversal to
implement `compute-object-sizes`. Finally, the GC can now perform a
fused `collect` and `compute-object-sizes` in a single traversal.
Also improve the way that locked objects are detected during GC. This
can make a significant difference (on the order of 10-20% for a full
collection) when locked objects are long-lived.

The MRG32k3a generator is fast when using unboxed floating-point
arithemtic. Since the Scheme compiler doesn't yet support that,
build MRG32k3a into the kernel and provide access via
`pseudo-random-generator` functions.

Merging ".o" files to one "kernel.o" can be convenient for further
linking, but it requires running `ld` directly. Running `ld` directly
sometimes runs into a mismatch between the C compiler and the default
`ld`. It's better to use the more typical approach of collecting
objects into an archive.

To support a more minimal build enviornment, offer the possibility of
building without "curses.h" and "libcurses" (which disables the
expeditor, although the expeditor's code is still included).

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

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
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.
