Andi,

I don't think the test is broken.  HAVE_SYS_RESOURCE_H is supposed to
be defined in confdefs.h (if your system has it) and autoconf prepends
confdefs.h to the source code above.  (Take a look at the resulting C
code in the generated configure file.)  All of my platforms correctly
pass this test.  E.g. on redhat-linux:

 > checking whether getrlimit must be declared... no
 > checking whether setrlimit must be declared... no
 > checking whether getrusage must be declared... no


Would you please look in config.log and show me exactly what is going
wrong on your system?  This test shouldn't be failing, but if it is
I'd like to see the error message, etc.
