wine-devel (1.3.26) fails to compile on NetBSD 5.0.1.

The compilation fails with the following errors:

mesh.o: In function `load_skin_mesh_from_xof':
mesh.c:(.text+0x3b96): undefined reference to `fmaxf'
mesh.c:(.text+0x3ba4): undefined reference to `fminf'

winegcc: cc failed

This is because fmin and fmax functions do not exist prior to NetBSD 5.1.

Build wine-devel from pkgsrc 2011Q2,Q3 or current on a NetBSD system prior to 
I have solved the problem using MIN and MAX from <sys/param.h>.
Hopefully it is a close enough approximation.  It seems to work well.

I hope this fixes the problem for others, it has for me.
