The idea is that gcc doesn't trust the syste compiler, so you build
the first version with no optimization (safer), then use that gcc to
build a new version with full optimization.  Since djgpp *is* gcc, you
don't need the second step.

To do the second step, just make a "stage1" directory, move gcc.exe
(renamed from xgcc.exe), cc1.exe, and cpp.exe (renamed from cccp.exe)
to the stage1 directory, do "rm *.o xgcc cc1 cccp" and then follow the
stage 2 instructions.

djgpp V2 provides its own headers; you do not use the ones from gcc.
