Subject: [PATCH] Port to compilers that moan about K&R func decls
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|

|
||
* lib/autoconf/c.m4 (AC_LANG_CALL, AC_LANG_FUNC_LINK_TRY):
|
||
Use '(void)' rather than '()' in function prototypes, as the latter
|
||
provokes fatal errors in some compilers nowadays.
|
||
* lib/autoconf/functions.m4 (AC_FUNC_STRTOD):
|
||
* tests/fortran.at (AC_F77_DUMMY_MAIN usage):
|
||
* tests/semantics.at (AC_CHECK_DECLS):
|
||
Don’t use () in a function decl.
