problem compiling HP-UX 11.11 using gcc

I thought I had some problems earlier with some version of gcc 4.x.x

I installed gcc 4.1.0 and got

gcc -g -O -D_REENTRANT  -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -DHPUX -I. 
 -I
/home/hobbit/snapshot/include -I/usr/local/include -DBBGEN_SSL  -I/usr/local/inc
lude   -c -o bbtest-net.o bbtest-net.c
bbtest-net.c: In function 'send_rpcinfo_results':
bbtest-net.c:1788: warning: assignment makes pointer from integer without a 
cast
bbtest-net.c:1795: error: dereferencing pointer to incomplete type
