Non-sucking Win32 C compiler

I need a small (not bloated to hell, clean, not system ruining / service installing) compiler for tiny C programs with POSIX-like semantics (i.e. C library that doesn't suck and stuff like read() instead of ReadFileWEX(WHANDLE, WSHARINGMODE, WSECURITYCONTEXT, NULL, NULL, NULL, NULL) - true POSIX stuff like fork() et al is not needed).

Visual Studio or cygwin are out of the question. Some GCC distro like mingw might be OK depending on how much the installation sucks (ideally there wouldn't be any installation at all).

Any ideas or do I give up to ENTERPRISE-quality software?

Compiling for Windows is a different story. What GCCs are available for Windows? MinGW and Cygwin (and DJGPP, but I haven't actually tried that one). MinGW is a piece of bug-ridden shit, and it wouldn't surprise me if they didn't use Cygwin because of a licensing issue.
