[Qgis-developer] OS X trunk build issues

... Well, the problem is not isnan, that's just what r14601 mentioned. The problem is abs(), and this has come up before for OS X - I think it had something to do with the order of includes.
There are a lot of places in Qgis that use abs() (more than just the 2 interpolator sources changed in r14601), and they generally include cmath/math.h after most other includes. Strange, there is a lot of inconsistent use of the includes and function calls:
some always include cmath and use std::abs()
some conditionally include math.h for OS X and cmath for all other systems, and use abs() (without the std C++ namespace)
... so, cmath seems to work on OS X in those other parts of Qgis (maybe there were problems with cmath on older OS X systems?), so just always include cmath. Worked for me on 10.6, but should be checked on older systems (at least 10.5). I might be able to try that this week (I do need to build the 1.6 PPC package still).
