Its a hack. I can't for the life of me find that "space" issue. So I hacked/patched the prebuilt configure to just not do the check. This should be okay since its in the testsuite dir anyway which I guess we could have just skipped. Also, I should note, I forgot to say you should ask for a repo copy from devel/gdb6. -- ------------------------------------------------------------------------ Philip M.
