trunk: build failure with llvm-gcc-4.2 (rev >= 14226)

[su_v]

The latest 2geom update in rev 14226 breaks builds which use llvm-gcc-4.2 on OS X 10.7.5. Compiling with clang (based on LLVM 3.1svn) works ok though, on the same system. Both compilers are provided by Xcode (4.3.2).

[su_v (suv-lp)]

'2geom/bezier.cpp' compiles successfully with r14327, but the build next fails in '2geom/path.cpp'. The attached build log is with boost 1.58.0; a similar build failure happens with boost 1.49.0 (different build env with older versions of dependencies).

[su_v (suv-lp)]

Attached is the full build log of 'make -k' (clean build) to spot any other obvious build failures with llvm-gcc-4.2 (AFAICT 'src/2geom/bezier.cpp' seems to be the only one).

Build fix confirmed (rev 14247) - thank you for your patience and time to continue supporting older compilers for now!
