My new gcc 3.1 uses old header files...

Hi,

With gcc 3.x, the location of many header files moved -- thus, if you
install gcc 3.x over 2.9x, some of the old header files will remain and
cause compilation problems.

I install each version of the compiler to a separate directory tree, using
the
--prefix=/opt/gcc-3.2.1 option on configure.

I have maintain a /opt/gcc link that maps to the version of the compiler I
use, and use that in setting my LD_LIBRARY_PATH, INCLUDE, LIB, and PATH
variables. By changing what /opt/gcc points to allows me to switch between
compiler versions easily.
