C / C++ Language Standards

[João Lopes]

Hi,

I am trying to understand what "versions" of C and C++ exists, and what
are supported by GCC.

    *Language Standards Supported by GCC*
    http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Standards.html#Standards
    *Options Controlling C Dialect*
    http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/C-Dialect-Options.html


For example, i can say "At project X we will use PHP 5.1, or JAVA 1.5", 
but if i use C++ what can i say ?
Google tells me about two C++ Standards ( C++98 / C++03 ) / /and two C
Standards ( C89 / C99 ),  so i can say this :

"I will use C++ ISO98 on project X, by using GCC with *-std=**c++98*"
"I will use C     ISO99 on project X, by using GCC with  *-std=**c99*"

Thanks,
João Lopes
