Mumit:
I have version B20 on NT 4.0 (gcc -v gives: gcc version egcs-2.91.57
19980901 (egcs-1.1 release), but not sure if its relevant here)
I think there is an error in a.out.h
(...cygwin-b20/H-i586-cygwin32/i586-cygwin32/include/a.out.h)
Near the end of the file I have the following defined:
#define ISPTR(x) (((x) & N_TMASK) =3D=3D (DT_PTR << N_BTSHFT))
#define ISFCN(x) (((x) & N_TMASK) =3D=3D (DT_FCN << N_BTSHFT))
#define ISARY(x) (((x) & N_TMASK) =3D=3D (DT_ARY << N_BTSHFT))
gcc complains about the =3D=3D bits (understandably, it says "non-digits in
number and not hexadecimal"), should these not be:
#define ISPTR(x) (((x) & N_TMASK) == (DT_PTR << N_BTSHFT))
#define ISFCN(x) (((x) & N_TMASK) == (DT_FCN << N_BTSHFT))
#define ISARY(x) (((x) & N_TMASK) == (DT_ARY << N_BTSHFT))
What do you think? (unless my version of cygnus unpacked badly, but I don't
think so)

Wow. It's kind of you to call this a "possible error". This is an
obvious boo boo on our part. Thanks for pointing it out. I've fixed
the problem in our development sources.
