@node ax_func_getopt_long
@unnumberedsec ax_func_getopt_long
@majorheading Synopsis
@smallexample
AX_FUNC_GETOPT_LONG
@end smallexample
@majorheading Description
Check for getopt_long support.
This assume that the standard getopt.h file (from GNU libc) is available
as lib/gnugetopt.h. If needed, this file will be linked as getopt.h, but
we want to default to the system's getopt.h file. (See
http://sources.redhat.com/ml/automake/2000-09/msg00041.html for an
explanation about why using the system's getopt.h file is important.)
