This is not a new switch. I have at home a printed version of the gcc
docs from V.2.6.3 and there is already this switch. This switch is
used by gcc for selecting the version of the called compilers
(cc1, cc1plus ...) which are stored on a unix machine in the
directories /usr/local/lib/gcc-lib/machine/version. 

With the current port of gcc to DJGPP it is not possible to use
this switch, because the default unix paths are not overwritten.

I have compiled my own gcc.exe with the paths setup to
$(DJDIR)/lib/gcc-lib/go32

and I have putted the sevearl versions in the directories
2.70
2.72

and so on. As default I'm using 2.72, but when I want to test
something with an other version, the only thing I have to is
to give gcc the -V2.70 switch and I can test something with
the 2.7.0 version of gcc.

BTW: It is described in gcc.info Node: Target Options
