[geos-devel] Geos CVS compilation with GCC 4.1, include error

[Matthieu DESILE]

Hello,

This morning I tried to compile geos from cvs and encountered several
errors of the same nature, where math functions were declared out of
scope (fabs, sin, ...), causing the compilation to abort.

It seems related to the not-inclusion of <cmath>, since its inclusion
gets rid of the errors.

Attached is a patch that includes <cmath> in the sources files that were
causing the compilation to abort.

Matthieu Desile.
