Subject: [PATCH] configure.ac: properly quote macro arguments
|
|
|
d7115b |
|
|
|
d7115b |
Autoconf 2.70+ is more picky about the quotation (even though with
|
|
|
d7115b |
previous versions the arguments should have been quoted, too). When we
|
|
|
d7115b |
don't quote macros inside the AC_CACHE_VAL macro - some of the Autoconf
|
|
|
d7115b |
initialization is wrongly ordered in ./configure script and we keep
|
|
|
d7115b |
seeing bugs like:
|
|
|
d7115b |
|
|
|
d7115b |
./configure: line 2165: ac_fn_c_try_run: command not found
