Subject: no way to test for dependent headers
Some libraries have headers that depend on either standard headers or other library headers. eg. libjpeg jpeglib.h requires size_t but doesn't include stddef.h itself. The solution I'll be using in Imager is as below, supplying the headers to test in order of dependence.
