Subject: [PATCH] configure.ac: properly evaluate ac_test_CFLAGS
|
||
|
|
|
||
|
|
Since autoconf 2.69 and
|
||
|
|
https://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=76754e04fce5f6a7701bec57b057020585df2ae3
|
||
|
|
ac_test_CFLAGS is set to ${CFLAGS+y} instead of ${CFLAGS+set}.
|
||
|
|
|
||
|
|
Just test that ac_test_CFLAGS is not empty, to support both cases.
