I think that because the installed fortran compiler is somehow broken
libtool detects that the compiler can not create shared libraries.
Fortran being tested last must overwrite the varaibles that were set for
the C and C++ compiler - so libtool does not create any shared libraries
at all. I'll look into it.

The "can_build_shared" shell variable is not tagged (not one var per compiler), so even though the C and C++ compilers would work, any broken compiler that comes later in the tests will cause libtool to not build shared libraries.

The code in question is a bit of a mess and may take a little sorting out.

In the meantime, if you build libtool with

configure F77=no FC=no; make

then it should disable the fortran tag. The installed libtool script then will not be able to build fortran code, but the use of the installed build script to build packages is not encouraged anyway.

Your users with broken fortran compilers will continue to see brokenness building other packages, since most autotools based build systems embed some version of libtool.
