How can I know all options (including defaults) which have been used 
in the various libraries distributed in binary form (libc, libm, 
libgcc, libgpc etc.) in djdev201.zip, gcc2721b.zip and gpc20b.zip.
I have tried to compile libc, libm and others from djlsr201.zip.
I have found bugs which indicate that the binaries have been compiled
with another version of the compiler/assembler. I have filed
a bug report, received the correct answer so that now it compiles fine.
But the length of the resulting library is different of what I obtain
either by issuing simply make after unzipping, or after addind -m486 
to the options contained in the file %djgpp%\src\gcc.opt 
I only want to know if the default options are best for my need:
I execute my programs only on a Pentium or very seldom a 486,
and I care only for speed, not for space or strange things like
IEEE compliance or possibility to run with no coproc. and an emulator
which cannot compute sin or cos (so I definitely want -ffast-math
evereywhere including in the libraries).
Thanks
