#2 compiling with gcc 4.3 fails

[Günter Dannoritzer]

When compiling drawtiming with gcc4.3 it fails with the error that in the file src/timing.cc 'strcasecmp' is not defined.

The attached patch solves the problem.

I can confirm that this patch fixes the build with gcc-4.4.1 on linux-2.6.x as well.
