There are two major GCC distributions for Windows:
- an emulated unix-alike environment; cygwin's GCC produces
executables which depend upon the emulation layer.
- a more minimal implementation to create native windows
executables that do not depend on an emulation layer.
(Missing some posix functionality though?)

In theory, yes; you may have to worry about variations in data
type/endianness. Depending on how complex/which apis you use (e.g.
process control/signals), cygwin is may be more suited to thi - although
unless your program is full GPL you may have licensing issues linking
with cygwin's emulation layer.
In practise, it might take a little work: it may be worth your while
investigating GNU autoconf.
