Description:
------------
Can't build --with-gmp on centos5. There is gmp.x86_64 4.1.4-10.el5

build error: too few arguments to function ‘__gmp_randinit_lc_2exp’

static void gmp_init_random(TSRMLS_D)
...
#if GMP_42_OR_NEWER
                gmp_randinit_mt(GMPG(rand_state));
#else
                gmp_randinit_lc_2exp(GMPG(rand_state), 32L);   << this line
#endif
...

last 5.4.35 5.5.19 and previous PHP 5.6.2 versions are ok

centos6 (gmp-4.3.1-7.el6_2.2.x86_64) builds without problem



Test script:
---------------
./configure ... --with-gmp ... && make
....
/usr/src/php-5.6.3/ext/gmp/gmp.c: In function ‘gmp_init_random’:
/usr/src/php-5.6.3/ext/gmp/gmp.c:1779: warning: passing argument 2 of ‘__gmp_randinit_lc_2exp’ makes pointer from integer without a cast
/usr/src/php-5.6.3/ext/gmp/gmp.c:1779: error: too few arguments to function ‘__gmp_randinit_lc_2exp’

Hi, this was my fault, and yes it was completely by accident.

I originally changed the default RNG to MT, without realising I had to cater for pre-4.2

When I added the conditional to use the LCG for pre-4.2 I missed the _size off. 

Sorry! Thanks for the patch Remi.
