-# gl_ABSOLUTE_HEADER(HEADER1 HEADER2 ...)
-# ---------------------------------------
-# 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.
