Bugzilla Bug 66193

gcc is compiled with USE=-f77 and I _do_ have f2c.

*** Bug 61201 has been marked as a duplicate of this bug. ***

same problem here

Could someone with a fortran-less gcc please check if he has  
/usr/lib/gcc-lib/i686-pc-linux-gnu/YOUR_VERSION_HERE/libg2c.so ?
When I link with this lib, all necessary symbols are found, but I am afraid it might be part of the Fortran option.

I don't have /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/libg2c.so

so the bypass would just be to install the fortran options ?

OK, added "f77" to use list, emerged gcc and now it builds correctly

Added the check from the newer version.
