I downloaded GCC 2.95 and Allegro 3.11 from ftp.cdrom.com, and am having a
nightmare trying to build the Allegro objects.

I have the path set and the environment variable set, and I believe that gcc
is installed properly, but when I run 'make' in the Allegro directory, it
fails on cpu.o with the following errors:

gcc -I. -Isrc -Iobj/djgpp -Wall -Wno-unused -m486 -O3 -ffast-math -fomit-fra
me-p
ointer -o obj/djgpp/cpu.o -c src/cpu.c
src/cpu.c: In function `check_cpu':

make.exe: *** [obj/djgpp/cpu.o] Error 1

If I remove the assembly routines from cpu.c and rerun 'make', everything
compiles fine, but obviously this is not an ideal solution! :o)

Is this related to what processor I'm running (a Pentium II 450)?  Should I
be using PGCC?  Is it simply a djgpp configuration issue?

Any pointers would be greatly appreciated.
