fuse() now expects a pointer as the argument to a fuse function. If
this is one of the functions that takes int, fuse() follows the pointer
and stores that value in the f_list slot, in the integer field of the
argument union. When the fuse goes off, do_fuses() recognizes the
function and passes it the integer field instead of the pointer.
This has the disadvantage of hard-coding the functions that require int
in daemon.c, but since the int is copied into f_list, it no longer has
to be in static or global memory, which simplifies several files.
Almost 1500 lines of compiler warnings remain, and the GCC developers
are already working on a new version with even more warnings turned on
by default.
MSVC complained that they might be used uninitialized. In some cases,
this might have been possible.
XRogue already has initializations for all these variables.
