Revision 1e58dba142c673c59fbb9d10aeecf62217d4fc9c authored by Ralf Wildenhues on 02 January 2011, 10:24:55 UTC, committed by Junio C Hamano on 14 February 2011, 18:55:15 UTC
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM
and friends.
Quoting autoconf-2.68/NEWS:
** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and
AC_RUN_IFELSE now warn if the first argument failed to use
AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file
contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have
a compelling reason why you cannot use AC_LANG_SOURCE but must
avoid the warning.
The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM}
take care to supply the previously computed set of #defines (and
include standard headers if so desired) for preprocessed languages
like C and C++.
In some cases, AC_LANG_PROGRAM is already used but not sufficiently
m4-quoted, so we just need to add another set of [quotes] to prevent
the autoconf warning from being triggered bogusly. Quoting all
arguments (except when calling special macros that need to be expanded
before recursion) is better style, anyway. These and more rules are
described in detail in 'info Autoconf "Programming in M4"'.
No change in the resulting config.mak.autogen after running
./configure intended.
