OK, but it should then reject the extra parameters, since it used to work.
In any case, I've changed the toolchain file:
----------------------------------------
# This is a CMake Toolchain file, required for cross-compiling using
# the Dignus cross-compilers on Windows, compiling for z/OS.
# Tell CMAKE the target system name
SET(CMAKE_SYSTEM_NAME "IBM_ZOS")
# Specify the cross-compilers
SET(CMAKE_C_COMPILER "regina")
SET(CMAKE_C_FLAGS "cc.rex dcc.exe")
SET(CMAKE_CXX_COMPILER "regina")
SET(CMAKE_CXX_FLAGS "cc.rex dcc.exe")
SET(CMAKE_C_CREATE_STATIC_LIBRARY "DAR -rv <TARGET> <OBJECTS>")
SET(CMAKE_CXX_LINK_EXECUTABLE "plink.exe
\"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
SET(CMAKE_C_LINK_EXECUTABLE "plink.exe
\"-S$ENV{DIGNUS_PROGRAM}/objs_norent/&M\" <OBJECTS> -o <TARGET>")
----------------------------------------
...and the behavior persists:
C:/Program Files/Regina/regina.exe cc.rex;dcc.exe CMakeCCompilerId.c
So it's not clear that that's a solution. I can't wrap the regina call because
what will I wrap it in? BAT is criminally busted -- it eats equals signs. So
later calls with -fwhatever=value will be broken.
If I comment out line 29 in CMakeDetermineCompilerId.cmake, it works with my
old toolchain file, but fails later with the new one, because it appears to
call "the compiler" without the "flags", and regina with no arguments produces
Help and exits.
Why are the semicolons being inserted? If I wanted semicolons between the
parameters, why wouldn't I just specify them?
Brad, your comment in the thread says:

Not sure what "on spaces" means, but again, it seems wrong to me that anything
is messing with my option format.

Correct. Those variables always hold only the compiler name.
When they are built from environment variables like CC and CXX
we split the arguments out into a separate variable. I think
the change in behavior came from this thread's change:
http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/27857
http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=fd38eda9
Read my first message in that thread for an explanation.
