Thanks for the explanation.

Last time I tried a more recent version of bash (from the package
system), it was breaking other things. I might try a manual
installation next, but won't have time in the near future.

There's no reason to leave gdb out of the release, we can just leave a
note in the docs that there are issues with OpenSolaris (not that it's
doc section needs to be any longer!). It's not a general
portability/cross-compilation issue for mingw-cross-env to solve, so
shouldn't affect release decisions.
