Synopsis

AX_ABSOLUTE_HEADER(HEADER1 HEADER2 ...)

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.
