[3] tells me that cid is [_a-zA-Z][_a-zA-Z0-9]* (which I think should be
in the FFI spec itself too) but I can't find a definition of fname in
it.

The C99 spec allows a lot of stuff I don't think makes sense after
#include, but a header file is specified by either "[^"\n]+" or
<[^>\n]+>. This only seems sensible if the "" or <> are also in the
impent string which is not the case in the examples.

Can someone clarify the intention for me please (and preferably also do
so in the FFI spec)?


Thanks
