Are you sure OpenCASCADE requires f77?
I looked into the source and didn't find any file like "*.f" or "*.for",
although of course they might have other extension or be generated
during the build process.
Also I can confirm it compiles with the base system gcc, although I
don't remember if I had gcc44 installed at the time, so it might also be
it picked f77 from gcc44 anyway.
The whole point of the above is that, due to gcc44's libstdc++ recently
becoming incompatible with older versions, if you mix different g++
versions in the same project, you'll get "Undefined symbol" errors when
starting your executable.
In my case, I'm linking (amongst others) against Boost and OpenCASCADE,
so I need them to use the same compiler (and use that myself).
Again, this is not a problem with OpenCASCADE only, but potentially
affects any C++ library which is build with gcc44.
