Fix a segfault in an IPv4-only case - realloc() may really, well,

"reallocate" memory even when the programmer only asks for a resizing
of the region.

Reported by:	Steve Ames <steve@energistic.com>

While I'm here, change the way SSL header and library paths are handled
to avoid specifically referencing /usr/lib and /usr/include; while
-STABLE's GCC shrugs this off, GCC 3.1 whines loudly about an explicit
-I/usr/include (and rightly so, IMHO).
