Switch from gcc-x.x to gcc-x.y

[Israfel_21]

Before continue, I declare that I know about the

export CC=gcc-x.y

I just want to know if there is a way to find out if the desired compiler is really working instead the default compiler, 'cause just after i enter the code I check the version of the compiler

gcc --ver

and stills shows me the default compiler version that I don't want to use.
I'm asking, of course, 'coz I'm having problems with a source code that claims to work well with gcc-2.95 and I'm not sure what to blame.
