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.

12 dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
13 dnl AC_REQUIRE([AC_FUNC_STRCOLL]) like AC_FUNC_STRCOLL
14 dnl The advantage is that the check for each of the headers/functions/decls
15 dnl will be put only once into the 'configure' file. It keeps the size of
16 dnl the 'configure' file down, and avoids redundant output when 'configure'
17 dnl is run.
18 dnl The drawback is that the checks cannot be conditionalized. If you write
19 dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
20 dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
21 dnl empty, and the check will be inserted before the body of the AC_DEFUNed
22 dnl function.
23
24 dnl This is like onceonly.m4, except that it uses diversions to named sections
25 dnl DEFAULTS and INIT_PREPARE in order to check all requested headers at once,
