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?

It's really not.

In the guise of G++, it's a really decent Sepples compiler (as those go) but for compiling C.... Well, I wouldn't feed it to my dog.
