[cffi-devel] Grovel default search path for include files

[Liam Healy]

System-installed header files sometimes are in different places
depending on the OS and method of installation.  In particular, the
file ffi.h that FSBV (http://repo.or.cz/w/fsbv.git) uses from libffi
seems to be in different places on OS X depending on how it was
installed (Apple native, Mac ports, etc.).  Not being a user of OS X,
it is difficult for me to know all the possible locations where this
file might end up.  Is it possible to specify that the groveler
should "search system-standard locations" for the header files
specified in include forms, analogous to load-foreign-library knowing
where to look for system libraries, and have it find the file based on
its knowledge of the places it might be for the current OS?

Thank you.
