Not sure if this really counts as a bug, but it might be worth fixing anyway.

If you set "$WM_COMPILER" = "Gcc42" (and I am using gcc4.2) and this is a 32 bit build, then wmake doesn't have a corresponding rules directory in the

OpenFOAM/OpenFOAM-1.4/wmake/rules

It looks like you can just copy the rules from linuxGcc4 to linuxGcc42.

Are there special rules for GCC4.2 that are not backwardly compatible with GCC4.0 ? Just curious.

Yes what you have done is correct. The reason we are not officially supporting gcc-4.2.0 is that it hasn't officially been released. I am now compiling and running with gcc version 4.2.0 20070317 (prerelease) and have not encountered any problems and the next version of OpenFOAM will be released compiled with gcc-4.2.?, whichever is the latest stable version at the time of release.
