Re: flexfax: compiling (not) with gcc 2.8.0 and libg++ 2.8.0

[Robert Colquhoun <rjc@trump.net.au>]

Hello Peter,

OK - Theres three problems with using gcc-2.8.0

1) Theres a number of C programs with void main() routines these need to be
changed to int main() theres a diff attached below to do this.

2) When using a pointer to call a class member function you need to specify
the pointer by using syntax similar to:
		&FaxClient::storeTemp
not	FaxClient::storeTemp
The above is not a real pointer unless the method is static it is an offset
pointer within the class.  This occurs in util/SendFaxClient.c++,
util/SendFaxJob.c++, hfaxd/OldProtocol.c++
(There's a whole array of this is OldProtocol.c++....) just add a '&' to
the front.

I would provide a diff for the above but i think it would break a number of
older compilers and maybe it would be better done another way.

3) Compiler Internal Error

            (reg:SI 9 %r9))) -1 (nil)
    (nil))
CopyQuality.c++:278: confused by earlier errors, bailing out


This might only be my compiler, i've got no idea how to fix this.
