+ vasprintf-gnu: New module.
+ * m4/vasprintf-posix.m4 (gl_FUNC_VASPRINTF_IS_POSIX): New macro,
+ extracted from gl_FUNC_VASPRINTF_POSIX.
+ (gl_FUNC_VASPRINTF_POSIX): Require it. Invoke
+ gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS.
+ * m4/vasprintf-gnu.m4: New file, based on m4/vasprintf-posix.m4.
+ * modules/vasprintf-gnu: New file, based on modules/vasnprintf-gnu.
+ * doc/glibc-functions/vasprintf.texi: Mention the new module.
+ * doc/glibc-functions/asprintf.texi: Likewise.

+Description:
+POSIX and GNU compatible vsprintf with automatic memory allocation.
+
+Comment:
+This module should not be used as a dependency from a test module,
+otherwise when this module occurs as a tests-related module, it will
+have side effects on the compilation of the 'vasnprintf' module, if
+that module occurs among the main modules in lib/.
