Not really, but g++ 2.95 is going to become much stricter WRT to C++
correctness.  Requiring -fpermissive for code that used to be accepted 
only with a warning is really intentional (not that I fully agree with 
it, but it's not up to me to decide it :-)

It might be nice to mention this trick somewhere in the FAQ.
Ok to install?

  complain that types are missing. These headers assume that omitting
  the type means 'int'; this assumption is wrong for C++.
  <p>
! g++ accepts such (illegal) constructs with the option -fpermissive;
! it will assume that missing type is 'int' (as defined by the C89
! standard).
  <p>
  Since the upcoming C99 standard also obsoletes the implicit type
  assumptions, the X11 headers have to get fixed eventually.

! <code>%{!fno-permissive:-fpermissive}</code> to the line just after
! `*cc1plus:' in the gcc specs file.
