9# This definition of AC_USE_SYSTEM_EXTENSIONS is stolen from CVS
10# Autoconf. Perhaps we can remove this once we can assume Autoconf
11# 2.62 or later everywhere, but since CVS Autoconf mutates rapidly
12# enough in this area it's likely we'll need to redefine
13# AC_USE_SYSTEM_EXTENSIONS for quite some time.
14
15# If autoconf reports a warning
16# warning: AC_COMPILE_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
17# or warning: AC_RUN_IFELSE was called before AC_USE_SYSTEM_EXTENSIONS
18# the fix is
19# 1) to ensure that AC_USE_SYSTEM_EXTENSIONS is never directly invoked
20# but always AC_REQUIREd,
21# 2) to ensure that for each occurrence of
22# AC_REQUIRE([AC_USE_SYSTEM_EXTENSIONS])
23# or
24# AC_REQUIRE([gl_USE_SYSTEM_EXTENSIONS])
25# the corresponding gnulib module description has 'extensions' among
26# its dependencies. This will ensure that the gl_USE_SYSTEM_EXTENSIONS
27# invocation occurs in gl_EARLY, not in gl_INIT.

7dnl From Paul Eggert and Derek Price.
8
9dnl Sets INCLUDE_NEXT and PRAGMA_SYSTEM_HEADER.
10dnl
11dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
12dnl 'include' otherwise.
13dnl
14dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
15dnl supports it in the special case that it is the first include directive in
16dnl the given file, or to 'include' otherwise.
17dnl
18dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
19dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
20dnl '#pragma GCC system_header' has the same effect as if the file was found
21dnl through the include search path specified with '-isystem' options (as
22dnl opposed to the search path specified with '-I' options). Namely, gcc
23dnl does not warn about some things, and on some systems (Solaris and Interix)
24dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
25dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
26dnl of plain '__STDC__'.
27dnl
28dnl PRAGMA_COLUMNS can be used in files that override system header files, so
29dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
30dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
31dnl has the effect of truncating the lines of that file and all files that it
32dnl includes to 80 columns) and the gnulib file has lines longer than 80
33dnl columns.

48 dnl file name. Despite these two bugs, include_next is used in the
