What is the problem here?

[John Neumöge]

I would like to compile gawk 3.0.4 using GCC 2.8.1 on HP-UX 10.20 and am
getting the following response:

gcc -c -DGAWK -I. -I.  -DHAVE_CONFIG_H -g -O2 array.c
In file included from
/usr/local/lib/gcc-lib/hppa1.1-hp-hpux10.20/2.8.1/include/stdio.h:8,
                 from awk.h:44,
                 from array.c:40:
/usr/include/sys/stdsyms.h:244: #error "Large Files (ILP32) not supported in
strict ANSI mode."
make: *** [array.o] Error 1

I am no GCC or C expert. Can anyone please tell me what the problem is here?

Thanks
