mingw gcc math.h problem

Hi.

I have dev-util/mingw-w32-20100605
If I try to compile digikam it errors out at

[  0%] Building CXX object
digikam/CMakeFiles/digikamcore.dir/__/libs/dimg/filters/sharp/matrix.obj

I figured out that it is caused by "abs" being already defined. I'm
not qualified in C/C++, so what and where needs to be adjusted?

(I did change
#ifndef _CRT_ABS_DEFINED
#define _CRT_ABS_DEFINED
  int __cdecl abs(int _X);
  long __cdecl labs(long _X);
#endif

to
#ifndef _CRT_ABS_DEFINED
#define _CRT_ABS_DEFINED
#ifndef abs
  int __cdecl abs(int _X);
#endif
#ifndef labs
  long __cdecl labs(long _X);
#endif
#endif

and this point seems to compile now)
