(sorry mosfet, did not check well the "To:" adress filled by gmail :( )
from cegcc web site:
What's the meaning of *arm-cegcc* and *arm-mingw32ce* ? They both describe
the target platform : we're building for an *ARM* processor, running the
Windows CE operating system, on unknown hardware (could be any brand of PDA
or smart phone). In the *cegcc* case, there's a portability layer; in the *
mingw32ce* case there isn't.
so basically cegcc is a newlib port that does this portability layer job.
But Vincent wants a native job. So the better is to contact this lib's
maintainers I think.
