 Sorry to say it only now, but none of these should work... Not any of them
is implemented for m68k in the plain vanilla GCC sources. The ISR-patches Ken
De Smet attached, must be added to the sources and the GCC built again with
them. Only after that the '__attribute__((interrupt))' will be recognized...

 The list in the clipped doc was taken from my own fixed manual, AFAIK no one
has added the ISR-support for FR30 and MN10300 into the official GCC sources.
I only have my own additions for them which nicely work 'on paper'...

 The 'wrapper'-method you used and Peter Barada suggested is the only way
with the 'official' GCC for 'm68k'. Implementing the attributes could however
be needed.

Cheers, Kai
