h264 for uclinux on cycloneIII 3C25

Under gcc/linux, the executable can have any extension, so it's not a problem per se.

It's problably a side effect of the build script. However, maybe it's worth taking a look a it.

I understood that you're using gcc in Linux.

What I meant is that, by the looks of it, whoever wrote the code was targeting just WIN32 and that may be the origin of your obscure problems.

From the __STDC_VERSION__ < 199901L condition, it also looks like the author was targeting C99.

Yet another dumb suggestion: try using the "c99" command to compile, instead of "gcc" -- it's an alias to gcc which makes it behave as a strict C99 compiler.
