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).
