+	* configure.in (-lm): No need to suppress libm on mingw, it's not
+	needed because it's empty, but including it does no harm.
+	(-lm): Look for "cos" instead of "main", since cos and friends are the
+	purpose of looking for libm.
+	(winsock etc): Test $host = *-*-mingw* rather than $MINGW32, autoconf
+	regards the latter as obsolete.
+	(AC_MINGW32): Remove test, $MINGW32 now unused.
+	(uint32_t): Look at HAVE_NETDB_H rather than hard-coding __MINGW32__
+	in the test program.
