warning with alloca.h and mingw-w64

[Vincent Torri]

Hey

I use 
http://www.gnu.org/software/autoconf/manual/autoconf.html#Particular-Functions

to declare alloca(). But with mingw-w64, I get that warning:

eina_prefix.c:34:0: warning: "alloca" redefined [enabled by default]
/home/torri/local/opt/mingw-w64-x86_32/bin/../lib/gcc/i686-w64-mingw32/4.7.0/../../../../i686-w64-mingw32/include/malloc.h:183:0: 
note: this is the location of the previous definition

the line that gives the warning is:

# define alloca __builtin_alloca

I don't know if it's important or not (it's just a warning) but i prefer 
telling you that there's a warning

regards

Vincent Torri
