Sorry for previous unfinished e-mail.

This is clearly a change of behavior but from my point of view it is a change
of "unsupported and/or unexpected" behaviour.

I think CMAKE_[C|CXX]_COMPILER vars are supposed to contain
a command not command + list of args.
If I'm wrong please someone (Alex, Bill,...) just tell me.

Doesn't
SET(CMAKE_C_COMPILER   "regina.exe cc.rex dcc.exe")
SET(CMAKE_CXX_COMPILER "regina.exe cc.rex dcxx.exe")
works for you?

If not I would say that you may either create a wrapper script which
make the triplet
a single command or may be you should:
SET(CMAKE_C_COMPILER   "regina.exe")
SET(CMAKE_C_FLAGS "cc.rex dcc.exe"
