This function is a wrapper around waf's check_python_header. It avoids searching more than once for the headers bringing a small speed improvement and a better lisibility of the logs. But it's mainly to avoid a nasty bug when python libraries are in path pointed by python_LIBPL (ie. /usr/local/lib/python2.6/config/) instead of python_LIBDIR (ie. /usr/local/lib). On the first call waf will correctly find that in order to link with python libs it needs to add -L$python_LIBPL. But on the next calls of check_python_headers, waf will use both the current library path value (ie. -L/usr/local/lib/python2.6/config) and -L$python_LIBDIR (ie. /usr/local/lib/) which will make him beleive that python libraries are in $python_LIBDIR which at the end will make the final link test fails in check_python_headers as it will not use the good directory. So by avoiding calling check_python_headers more than once we avoid making waf fooling itself.
