Since you are using a IBM C compiler on IBM AIX, you should ask in a IBM forum. Or try it on OpenSolaris.
But as a tip you should look at the line numbers in error (such as hw_pk11.c line 786) and see what's on that line. If you are compiling C source code, it may help if you familiarize yourself with the C programming language. Post the contents of that line to the forum. -- This message posted from opensolaris.org
