Please provide the exact steps needed to reproduce this problem (i.e., a
complete small testcase, the exact compilation command line, or, better
yet, a Makefile).  Also, we need information on what packages are
installed on your system, and what your environment contains -- both will
be present in the output of "cygcheck -svr", which you should have
attached to your message anyway, as per <http://cygwin.com/problems.html>.

It means "the man page for 'system' in section 3 of the manual".  Try "man
-s 3 system" (normally, "man system" should do this anyway).
