I've tried to compile and run the following simple program:

#include <stdio.h>
int main() { printf("Ok\n"); exit(0); }

I used the command:

        gcc -O -D_HPUX_SOURCE -Aa -L/lib/pa1.1 -DUINT32_MAX_BROKEN -fno-strict-a
liasing -I/usr/local/include -o try -L/usr/local/lib try.c -lnsl -lnm -lndbm -lm
alloc -ldld -lm -lc -lndir -lcrypt -lsec
        ./try

and I got the following output:

*Initialization*:1: missing token-sequence in `#assert'
I can't compile the test program.
(The supplied flags or libraries might be incorrect.)

You have a BIG problem.  Shall I abort Configure [y]
Ok.  Stopping Configure.
