Build failed

[Michael Reed]

Trying to build gdb-4.18  with gcc-2.95.2 on AIX 4.3 which configured as 
"powerpc-ibm-aix4.3.3.0" gave the following error:

make[1]: Entering directory `/prod_data/epha/home/src/build/mmalloc'
gcc -c -g -O2 -DHAVE_UNISTD_H=1 -DHAVE_GETPAGESIZE=1 -DHAVE_LIMITS_H=1 
-DHAVE_STDDEF_H=1  -I. -I../../gdb-4.18/mmalloc/../include 
../../gdb-4.18/mmalloc/mm.c
In file included from ../../gdb-4.18/mmalloc/mm.c:37:
../../gdb-4.18/mmalloc/sbrk-sup.c:27: conflicting types for `sbrk'
/usr/include/unistd.h:586: previous declaration of `sbrk'

Temporarily fixed this by changing line 27 of sbrk-sup.c from

extern PTR sbrk PARAMS ((int));

to

extern PTR sbrk PARAMS ((intptr_t));

This allowed gdb to build.  However, when I tried to use it to debug the 
following program

$ cat > s.c
int main() { return 0;}
$ gcc -ggdb3 -o s s.c
$ gdb s

Any help would be appreciated.
