gcc compile?

[Xu, Qiang (XSSC SGP)]

hi, all: 
i have downloaded the full package of gcc 2.95.3, if i want to install it by
the method of "make" and "make install", is any previous gcc version before
2.95.3 is required? 
and which version is the minimal requirement to compile v2.95.3? 

and to compile this previous version, is any version before it is a
requirement? 

if yes, it seems an endless chain. 

is there any stand-alone version of gcc? (stand-alone here means if there is
only the inborn cc compiler with a UNIX system, and this UNIX system hasn't
installed any version of gcc before, can i compile gcc2.95.3 on it?)

i checked the installation notes in the gcc 2.95.3 package, but it didn't
talk of the minimal requirements. 

any idea?

thanks, 

Regards,
Xu Qiang
