vmailmgr-glibc-2.10+.patch

VMailMgr's checkvpw fails to build on systems with glibc-2.10+.
strcasestr() in checkvpw.cc also exists in glibc. Before glibc-2.10,
they were declared identical, so it still built. glibc-2.10 started
to declare it as "const char *" instead of "char *" though, so the
build fails. This patch simply removes strcasestr:
