I got exact the same version on both Windows(MinGW) and Red Hat. One
interesting note is that the result of 'gcc --version' command is not
exact the same as 'gcc -v' command. In fact, when using command g++ --
version, the result is:

$ g++ --version
g++.exe (GCC) 4.3.4 20090511 for GNAT GPL 2009 (20090511)

However, if command 'g++ -v' is used, the result is quite different as
shown:

$ g++ -v
