i tried to compile libmpc svn rev 477 but failed
 

i think this error maybe come from conflicts between mingw header and msys header.

==========
mingw stdint.h
typedef signed char int8_t;

msys types.h
typedef char int8_t;
================

even if i resolve this conflicts
new error(ctype related undefined) occured.
welcome any suggestions.

What did you select as target in cmake? If you select mingw makefiles, you should use mingw32-make.exe, if you select msys makefiles everything should be compiled with the regular msys make.exe
