[Bug 858425] [NEW] g++ has a new syntax complaint

[Alex Coventry]

Public bug reported:

Not 100% certain this is a bug, as opposed to some new C++/g++
development.  But the following sequence of commands runs without error
in g++ 4.4.3 on ubuntu lynx, while in g++ 4.5.2 on ubuntu natty it fails
with the complaint

  g++ -c -Wall -O3   PB.cpp
  PB.cpp: In function ‘int main(int, char**)’:
  PB.cpp:1076:22: error: cannot call constructor ‘Random::Random’ directly
  PB.cpp:1076:22: error:   for a function-style cast, remove the redundant ‘::Random’
  
Here is the sequence of commands which produces the above error on
ubuntu natty:

  met% wget http://megasun.bch.umontreal.ca/People/lartillot/www/phylobayes3.3b.tar.gz
  met% tar zxf phylobayes3.3b.tar.gz 
  met% cd phylobayes3.3b/sources/
  met% make

Hope this helps.
