[Octave-bug-tracker] [bug #48531] LTO warnings in liboctave

[John W. Eaton]

Follow-up Comment #6, bug #48531 (project octave):

I'm attaching a preliminary version.  I think everything is fixed except the
lsode common blocks.  I don't think there is actually a problem there, but we
can still fix it.  I thought it would be trivial to just make all the
declarations of the common blocks identical, but there is at least one
instance where doing that would put the a subroutine parameter in a common
block so a little more thought will be needed there about exactly what the
best fix is.

I don't intend to use the "iso_c_binding" things unless forced.

If some system fails to allow a reinterpret_cast from "std::complex<double>"
to "double _Complex*", then I think it should be possible to fix by using some
other macro definition(s).  Or, if some different approach is needed, at least
all of the locations that need to be fix may now be identified easily.
