If you are refering to win32lib.h, oldnames.h there are version in the TL svn
repository and in metapost-1.000. For my experiment with pdftex I created
a src/win32 directory for the headers from metapost. There were some
conflicts. I ended up with:
export CC=i586-mingw32-gcc \
CFLAGS='-DHAVE_BOOLEAN -D_UWIN -Dtrue=1 -Dfalse=0 -DTRUE=1
-DFALSE=0 -I../../../../src/win32 -I../../../src/win32' \
in build-win32.sh. The -DHAVE_BOOLEAN is for kpathsea, the -D_UWIN is for the
This is enough to build many .o files, but there are problems
with the Makefiles that generate a target (e.g. win32) tangleboot on a
and also missing library routines.
I think there are some underlying problems with excessive use of
#ifdef win32 rather than #ifndef HAVE_SOME_POSIX_CAPABILITY
that tend to enforce dependencies on a particular build environment.

I was hoping that pdftex would be stable by now -- but between bugs
in pdftex and in the libraries it needs rebuilding rather too often.

Sounds like a plan.
