[PATCH] Work-around to prevent an error (Cross-compiler-build) about caddr_t

[Markus Eisenmann]

Hi! 

Building a cross-compiler of GCC (based on mingw-host) will end with a compiler-error, because 
(in this case) the GCC-build uses a generated header-file which defines a macro for caddr_t . 

Caused by wrong detection wheter caddr_t is already known; autotools is checking the 
host header-files and not newlib provided definitions :-) 

Up to now, I've used a small patch on sys\types.h as work-around; I.e. undefining caddr_t 

Maybe this should be included in the trunk ... :
