[Discuss-gnuradio] gcc4

From: cswiger
Subject: [Discuss-gnuradio] gcc4

the README suggests gcc 3.2 and 3.4.  The latest Fedora Redhat Linux
has gcc4. Is that supposed to work?

Looks like something with banchmark_dotproc.cc has compiler version
issues, then something else gets
undefined reference to `gr_fxpt::TWO_TO_THE_31'
and gr_fxpt::PI and that's all folks.
