I saw patch from Mark.

wrong links to newlib related header files were created only when builing 
Linux to DJGPP cross-compiler. There were no such problem when I
tried to cross-build native compiler for DJGPP under Linux (I got correct
links in this situation)

Didn't really test C rather than with cross-building GCC itself, but with
C++ I had libstdc++-v3 related problems:
	 
crashes in iostream related static constructors at program startup both
when compiled with Linux to DJGPP cross-compiler and native compiler for
DJGPP.
