Re: bug: "gcc -std=gnu99" passes AC_PROG_CC_C11

[Adrian Bunk]

This bug is still present after the AC_PROG_CC changes
(that didn't touch the relevant code at all):

<--  snip  -->

$ autoconf --version
autoconf (GNU Autoconf) 2.69.33-6cd96
...
$ gcc --version
gcc (Debian 4.7.2-2) 4.7.2
...
$ cat configure.ac 
AC_INIT
AC_PROG_CC
$ autoconf
$ CC="gcc -std=gnu99" ./configure
checking for gcc... gcc -std=gnu99
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc -std=gnu99 accepts -g... yes
checking for gcc -std=gnu99 option to accept ISO C11... none needed
$ grep ^CC config.log 
CC='gcc -std=gnu99'
$ 

<--  snip  -->
