Correct. First, link.exe does not use -l<libname> to link in libraries, it uses lib<name>.lib (similar to how gcc allows you to specify the full filename of a lib<name>.a static library). Second, there is no math lib necessary at all. The problem with this check is that it tries link.exe -lm test.c, which succeeds while warning that -lm is a non-existing option. From then on, it keeps inserting -lm everywhere (and thus causes that warning ad infinitum). I fix that by trying without -lm before using -lm.
