[Coco] Announcement : Nitros-9 C compiler tool cross chain for Linux

[Walter Zambotti]

Bill

I managed to get all but cc253 to compile under mingw32 with some changes to the makefiles and some minor changes to the referenced include files.

However mingw does not provide any substitute for:

	Fork
	Kill
	Waitpid
Or
	OS9fork

So the runit (run child unit program) function will need to be rewritten.

Walter, thanks for the info. I may try creating makefiles for everything like the NitrOS9 repo. This could simplify the process.

Tip:

There is no overall make file.  You'll have to go into the build directory for each component and type make.

Make sure you are using a 32 bit build environment. It simply won't work in 64 bit!
