Subject: strtoll: Work around a bug on native Windows and Minix.

* lib/stdlib.in.h (strtoll): Override if REPLACE_STRTOLL is 1.
* m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize REPLACE_STRTOLL.
* m4/strtoll.m4 (gl_FUNC_STRTOLL): Test whether strtoll works. Set
REPLACE_STRTOLL.
* modules/stdlib (Makefile.am): Substitute REPLACE_STRTOLL.
* modules/strtoll (configure.ac): Test REPLACE_STRTOLL.
* tests/test-strtoll.c (main): Add tests of hexadecimal integer syntax.
* doc/posix-functions/strtoll.texi: Mention the bug.
