And just to make your life even more miserable, there will be ABI
breakage in libgfortran in the not too far future. IIRC 4.2 bumped
the so version from 4.1, and it will probably happen again for 4.3.
It already happened.
Another thing you might want to consider is that now that you're
providing a Fortran 95 compiler, presumably other developers will
want to add F95 libraries that provide module files (say, the F90
interface to netcdf, lapack95 etc.). Coming up with a policy for
these .mod files (where should they go?) might be easier now than a
few years later when you have a few dozen libraries doing it their
own way. IIRC the default is to put them into the normal include
directories
Nope. The module files for the standard headers (including Fortran
standard headers and the OpenMP module) was decided to be ${prefix}/
lib/gcc/${target-triplet}/${version}/${multilib}/finclude because it
depends on both the target, GCC version and multilib settings.
Now, I agree with Jane: while you don't want to put any other headers
in there, you need to come up with something :)
