problem detecting gcc version 4.3 prerelease, which is default version with Suse 11.0

Hi,
when running configure on orocos-rtt-1.6.0, I got
{{{
ERROR: You seem to be using gcc version:
4.3

CMake Error at config/global_setup.cmake:41 (MESSAGE):
ERROR: For gcc, Orocos requires version 4.x or 3.x
}}}

This is because gcc 4.3.1 (prerelease), the default with SUSE 11.0, provides 4.3 to -dumpversion, instead of 4.3.x
{{{
daniel@linux-i8nx:~/deps/orocos/orocos-rtt-1.6.0-boost-test/build> g++ --version
g++ (SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036]

4.3
}}}

The problem is at config/global_setup.cmake, because it checks CXX_VERSION MATCHES "4\\.[0-9]\\.[0-9]". I tried, to make the minor number optional, but didn't succeed

Thanks for reporting. The patch in attachment will fix this.
