RedHat 7.0 uses gcc 2.96 which has some incompatibility problems with
c++. Currently, this package does not not compile with this version of
c++.

However, RedHat 7.0 does include egcs++ (gcc 2.95) which works
fine. To use this version of the compiler, prefix the configure and
make commands with CC=egcs++. For example:
  CC=egcs++ ./configure ...
  CC=egcs++ ./make
