Yes, it makes a difference. In that case, the default version is 2.4.0 (e.g. the same as if you'd typed "-V 2.4.0"). If you wish to install a new version but have the default remain the old version, you could save your old "gcc" frontend somewhere, install the new compiler, and put the old "gcc" back. Or you could hack the sources. I don't recommend this unless you really know what you're doing though. For example, in going from 2.3.3 to 2.4.0 on Suns, the type of size_t has changed (Sun claims it is "int", which violates ANSI C; as of 2.4.0, it is "unsigned long" with fixincludes fixing the Sun headers to match). For C++ users, mixing the versions is likely to be painful; similarly for C users who use prototypes everywhere. -- Joe Buck jbuck@ohm.EECS.Berkeley.EDU
