gdb/gdb-6.8-bz377541-fortran-dynamic-arrays.patch
Jan Kratochvil 25ff8a1663 - Upgrade to the upstream gdb-6.8 prerelease.
- Cleanup the leftover `.orig' files during %prep.
- Add expat-devel check by the configure script (for the other-arch
    builds).
- `--with testsuite' now also BuildRequires: fpc
- Backport fix of a segfault + PIE regression since 6.7.1 on PIE
    executables.
- Update the printed GDB version string to be Fedora specific.
