hmm, maybe I can abuse your knowledge with compilers for this one :)

The reason for tying the compiler versions so strict is that Octave adds
the FLIBS (Fortran) found at configure time into one of its scripts for
later use (building plugins, either in Debian or on the enduser's
machine). 

FLIBS looks like this:
  -L/usr/lib/gcc/x86_64-linux-gnu/4.3.2
  -L/usr/lib/gcc/x86_64-linux-gnu/4.3.2/../../../../lib -L/lib/../lib
  -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/4.3.2/../../.. -lhdf5
  -lz -lgfortranbegin -lgfortran -lm

Do you know if it's possible to get rid of the version specific compiler
paths here? The macro is the default AC_F77_LIBRARY_LDFLAGS.

Thanks
