Hmmm ok. I have now solved my problem with compiling on Solaris 2.5.1 for the x86. The problem was with gcc. Apparently fixincludes (Which I did run...) did not work quite correctly. Instead I downloaded a current version of gcc which was compiled on 2.5.1 for the x86 and didn't need fixincludes run. Everything worked fine then. I found the binaries at ftp://x86.cs.duke.edu/pub/solaris-x86/bins/gcc-2.7.2.2.tar.gz Just in case anyone else has this problem. thanks. Greg. tech@uafs.com
