AX_ABSOLUTE_HEADER(HEADER1 HEADER2 ...)
@end smallexample

@majorheading Description

Find the absolute name of a header file, assuming the header exists. If
the header were sys/inttypes.h, this macro would define
ABSOLUTE_SYS_INTTYPES_H to the `""' quoted absolute name of
sys/inttypes.h in config.h (e.g. `#define ABSOLUTE_SYS_INTTYPES_H
"///usr/include/sys/inttypes.h"'). The three "///" are to pacify Sun C
5.8, which otherwise would say "warning: #include of /usr/include/...
may be non-portable". Use `""', not `<>', so that the /// cannot be
confused with a C99 comment.
