No problems, works for me.  As long as you call it "gcc", you should be
fine (AFAIK, everything in NetBSD uses "cc").  There were some problems
getting libg++ working, but you can check the mailing list archives for how
to beat that.  The sources/binaries on ftp.netbsd.org should work, but I
recall that a out-of-the-box build worked fine.
