No, finding libgfortran.spec at compile time works - it is all about 
finding it at run time.

I am not sure the bug is the same, but they are related. Both are about 
finding the .spec file at run time; once for the installed system and 
once for the test-suite run. My plan is first to fix the first issue, 
namely where the compiler searches for the library and then to revisit 
the test suite issue.

The changes made can be shown via:
   svn diff -r166824:166825 gcc/testsuite/lib/gfortran.exp

The changes are needed if the compiler is not installed, i.e. the 
libraries are only in the build directory. In this case "gfortran" (the 
driver) needs to be able to find the libgfortran.spec file based on the 
passed -L<dir>. The patch (cf. svn diff) is doing this, but seems to 
break the test suite in some cases.
