If these are meant to be the SONAMEs of libc and libdl (with "/" 
prepended), you should use LIBC_SO and LIBDL_SO from <gnu/lib-names.h>.  
Some configurations have different SONAMEs (look for libc= and libdl= in 
shlib-versions files).  Also watch out for any interaction with Florian's 
patches to move libdl into libc.

Throughout this patch, there should be a space before '(' in function 
calls; tests should follow GNU style, like other glibc code.  (In the GCC 
and GDB testsuites, it's useful to have code with a range of different 
styles, to make sure those tools work well with such code, but that 
doesn't apply to the glibc testsuite.)

Same comment about using <gnu/lib-names.h> applies here.

Again, GNU style fixes.  Return type on its own line, space before '(', 
open braces on their own lines (and indented from the "if").
