Patch to prevent tilde crashing readline

[Martin Simmons <qqxnjvamvxwx@spammotel.com>]

Here is a patch to the gdb readline to fix a typo in the MinGW changes.  The
current CVS gdb segfaults on x86_64 FC3 Linux whenever ~ is used, e.g.

source ~martin/my-commands

The segfault is in strlen(), called from tilde_expand(), because
tilde_expand_word() returns NULL when HAVE_GETPWNAM is not defined
(i.e. always!).  Someone should fix tilde_expand_word() to do the existing
else clause in this case.

Please CC me on any replies as I am not subscribed.
