Sorry about that.  Also, we need m4/string_h.m4.  Here they are:

::::::::::::::
modules/string

Description:
A GNU-like <string.h>.

Files:
lib/string_.h
m4/string_h.m4

Depends-on:
absolute-header
extensions

configure.ac:
gl_HEADER_STRING_H

Makefile.am:
BUILT_SOURCES += string.h

# We need the following in order to create <string.h> when the system
# doesn't have one that works with the given compiler.
string.h: string_.h
