26_numerics/c99_classification_macros_c.cc is broken

[Andreas Jaeger]

Running the testsuite on CVS mainline with i686-linux-gnu I get this
error messages:

compiler exited with status 1

The problem is that c99_classification_macros_c.cc has for example in
line 34 (first error):
void fpclassify() { }

But glibc implements fpclassify as a macro, following ISO C99
("7.12.3.1  The fpclassify macro" (note the title)).

So, what should this testcase do?  Should it test that the
functions/macros exist?  In that case the file should not declare the
functions itself but just call them.
