gdb/patches/gdb-6.5-sharedlibrary-path.patch

   1 If you provided some relative path to the shared library, such as with
   2         export LD_LIBRARY_PATH=.
   3 then gdb would fail to match the shared library name during the TLS lookup.

   6 Dropped the workaround/fix for gdb-6.8.50.20081128 - is it still needed?

   9 The testsuite needs `gdb-6.3-bz146810-solib_absolute_prefix_is_empty.patch'.
  10 The testsuite needs `gdb-6.5-tls-of-separate-debuginfo.patch'.
