how to check for HAVE_FOO_PROTO ?

[Alexander Neundorf]

Hi,

in kdelibs/ there are configure checks for really a lot of stuff.
What does HAVE_FOO_PROTO mean ? (with FOO = GETHOSTNAME, INITGROUPS, MKDTEMP, 
MKSTEMP, RANDOM and others)
How should be tested for it ?

cmake has a check_function_exists(), which tries to compile and link a small 
executable calling this function. But what should be done for 
HAVE_FOO_PROTO ?

Bye
Alex
