gcc.dg/pr51867.c currently FAILs on Solaris 8 and 9:
FAIL: gcc.dg/pr51867.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/pr51867.c:7:12: warning: incomp
atible implicit declaration of built-in function 'sqrtf' [enabled by default]
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.dg/pr51867.c:11:12: warning: incom
patible implicit declaration of built-in function 'sqrtf' [enabled by default]
which is no wonder since those targets lack a C99 libm. This can easily
be avoided by simply declaring sqrtf directly, which the following patch
does.
Tested with the appropriate runtest invocations on i386-pc-solaris2.8,
i386-pc-solaris2.11, and x86_64-unknown-linux-gnu, installed on
mainline.
