[csw-maintainers] libsigc++ and studio vs. gcc

[Jan Holzhueter]

Hi,
since we have a new boost I though I would give rtorrent a new try :)
First thing is to build libtorrent which depends on libsigc++.
This is build with sun studio atm. The last time I looked at it you will
get other header files when you build with gcc.
Which now hit's me as I build libtorrent with gcc.
It fails with erros in the header files:

libtool: compile:  /opt/csw/bin/g++-4.6 -DHAVE_CONFIG_H -I. -I../../..
-I. -I./.. -I./../.. -I../../.. -I/opt/csw/include -O2 -pipe -m32
-march=pentiumpro -DNDEBUG -fvisibility=hidden -I/opt/csw/include

Should we build a second libsigc++ in /opt/csw/gxx or just rebuild with
gcc to /opt/csw/gxx
as I think we should default C++ stuff to gcc anyway?
