Hello,
I am happy to report that LyX137cvs2 actually runs on Win95 (an old
486, 16Mb memory!)... however, with a few caveats,
0/ installer breaks on running configure, as it did before on Win98...
1/ the already reported problems with the fonts in menus, etc...
2/ it only works when the environment variable lyx_dir_13x or the
-sysdir option
are set to the SHORT path of the LyX executable.
So apparently the wrapper to convert long to short paths on Win95
is still broken...
As promised, Luis, here is a standalone version of the paths thing for you
to play with. It was just missing a few #includes...
