9# gl_ABSOLUTE_HEADER(HEADER1 HEADER2 ...)
10# ---------------------------------------
11# Find the absolute name of a header file, assuming the header exists.
12# If the header were sys/inttypes.h, this macro would define
13# ABSOLUTE_SYS_INTTYPES_H to the `""' quoted absolute name of sys/inttypes.h
14# in config.h
15# (e.g. `#define ABSOLUTE_SYS_INTTYPES_H "///usr/include/sys/inttypes.h"').
16# The three "///" are to pacify Sun C 5.8, which otherwise would say
17# "warning: #include of /usr/include/... may be non-portable".
18# Use `""', not `<>', so that the /// cannot be confused with a C99 comment.
