It seems that there is missing int std::abs(int) in gcc 4.3.0. System is
Archlinux current.
Example output(from enblend cvs):
../../include/vigra/imageiteratoradapter.hxx:532: error: call of overloaded
‘abs(int&)’ is ambiguous
/usr/lib/gcc/i686-pc-linux-gnu/4.3.0/../../../../include/c++/4.3.0/cmath:99:
note: candidates are: double std::abs(double)
/usr/lib/gcc/i686-pc-linux-gnu/4.3.0/../../../../include/c++/4.3.0/cmath:103:
note: float std::abs(float)
/usr/lib/gcc/i686-pc-linux-gnu/4.3.0/../../../../include/c++/4.3.0/cmath:107:
note: long double std::abs(long double)
GCC version:
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../configure --prefix=/usr --enable-shared

--libdir=/usr/lib --libexecdir=/usr/lib --enable-clocale=gnu
--disable-libstdcxx-pch --with-tune=generic

------- Comment #1 from pcarlini at suse dot de 2008-04-12 19:29 -------
You want to include <cstdlib>: <cmath> only provides overloads for floating
point types (see 26.5 for details).
