Compile error: IRIX 6.2 w/ IDO

I tried compiling on a plain Indy R4400-200mhz system. The operating system is IRIX 6.2 w/ the rollup patch bundle. Compiler was the SGI IDO (development option), not MipsPro. I will probably drop GCC on the system and compile with that. I just thought I would let you know, it would rock to be able to compile PHP 4 + Apache with standard IDO. I plan to install MipsPro 7.x.x on a SGI and try to throw down with that...
