GCC and cygwin portable

Hi folks,

I am learning NSIS, in particular the portabilizing aspects of it.

I want to portabilize the entire gcc toolchain, including cygwin (the only non portable part, imho...). I also want to portabilize the PRC-Tools plugin (prc-tools.sf.net) to aid in my PalmOS development.
I have Dev-C++ for desktop developement, GCC wouuld be solely for Palm developmtn now that I think of it.

is this feasible? How would I go about doing this?

Later Daze,
