Re: [sigc] libsigc++ 1.9.13 fails on Solaris 9 sparc

[Damien Carbery <Damien Carbery Sun COM>]

My last message was too big (>40k) and may be held up or blocked so I am 
resending with gzip'd slot.h attached.

I made the following literal changes to sigc++/functors/slot.h:
LIBSIGC_TEMPLATE_PREFIX is now empty.
and
SIGC_WORKAROUND_OPERATOR_PARENTHESES is sun_forte_workaround
so you get lines like:
return (typed_rep->functor_). sun_forte_workaround<typename 
type_trait<T_arg1>::take>

When (incrementally) building test_slot.cc I get:
CC  -I. -I. -I.. -I.. -I..  -DG_HAVE_ISO_VARARGS -DG_IMPLEMENT_INLINES 
-I/opt/gnome-2.4/include  -g -c -o test_slot.o `test -f 'test_slot.cc' 
|| echo './'`test_slot.cc

FYI: I am out of the office from end of business today until Tuesday 
April 13th. If you need anything checked before then, get it to me by 
4:30pm Irish time today.
