Subject: [PATCH] configure.in: Some improvements for Solaris, expecially the
 swap plugin.

If Solaris is detected, "-D_POSIX_PTHREAD_SEMANTICS" will be added to
CPPFLAGS automatically now.

If sys/swap.h is not found, print a message suggesting to build a 64bit
binary. (sys/swap.h cannot be included when a 32bit binary is being built,
but it's most likely present under Solaris.)

Enable the swap plugin only if sys/swap.h has been found (when under
Solaris).
