The new gcc.dg/fstack-protector-strong.c testcase is currently failing
on Solaris/x86 like this:

FAIL: gcc.dg/fstack-protector-strong.c (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/fstack-protector-strong.c:113:13: warning: incompatible implicit declaration of built-in function 'alloca' [enabled by default]

Matching other testcases that use alloca, I've fixed it by explicitly
declaring alloca.

Tested with the appropriate runtest invocations on i386-pc-solaris2.11
and x86_64-unknown-linux-gnu, installed on mainline.

	* gcc.dg/fstack-protector-strong.c (alloca): Declare.

I'd say the test should just use __builtin_alloca instead.

Yea, let's go with that.  OK with that fix.  I


Ranier, if you run into others, they're pre-approved to be fixed this 
way as well.
