There used to be a flag -fdumpxref for the GNAT gcc C compiler that output .gli files, which gnatcoll.xref parsed just as it does .ali files for Ada code.

But that is apparently gone; 

gcc.exe: error: unrecognized command line option '-fdumpxref'

gnat/.../cc1.exe --help shows a flag -fxref, but that is also gone:

gcc.exe: warning: switch '-fxref' is no longer supported

So how do I use gnatcoll.xref with C code?
