I assume you're using Cygwin just as a host and using VxWorks cross-tools 
to build for the target. That said, I'm not sure what you mean by Cygwin
not recognizing environment variables, which it certainly does. Unless you
provide some examples of what you're trying to do and how these fail under
Cygwin, I'm afraid it'll be hard to find any help here.

Cygwin strives to emulate Unix systems, and you'll need to have some
understanding of Unix-like systems work.

Again, provide some examples please. There is no such thing as GCC order;
however, GNU linker is single-pass, and so you do need to provide the
object files and archive libraries in the right order on the command line
when linking.

umount.
