+	* configure.ac: Version 0.3.7 to match minor changes in gawk API.
+	* strhash.c: Must now include <sys/stat.h>.
+	* varinit.c: Include <sys/stat.h>.
+	(gawk_api_varinit_array): After installing an array, it is no longer
+	necessary to call sym_lookup, since sym_update now updates the
+	array_cookie value.

 	* configure.ac: Version 0.3.6.  All checks now pass on Linux and Cygwin.
