Ah HAH -- you're right, sort of, though I don't understand why it's this way.
With the code added that you suggested:
GOOD
!!!! C:/Program Files/Regina/regina.exe cc.rex dcc.exe CMakeCCompilerId.c
-- arg=[COMMAND]
-- arg=[C:/Program Files/Regina/regina.exe]
-- arg=[cc.rex dcc.exe]
-- arg=[CMakeCCompilerId.c]
-- arg=[WORKING_DIRECTORY]
-- arg=[C:/SVN/zFPE/CMakeFiles/CompilerIdC]
-- arg=[OUTPUT_VARIABLE]
-- arg=[CMAKE_C_COMPILER_ID_OUTPUT]
-- arg=[ERROR_VARIABLE]
-- arg=[CMAKE_C_COMPILER_ID_OUTPUT]
-- arg=[RESULT_VARIABLE]
-- arg=[CMAKE_C_COMPILER_ID_RESULT]
BAD
!!!! c:/Program Files/Regina/regina.exe cc.rex;dcc.exe CMakeCCompilerId.c

-- arg=[ERROR_VARIABLE]

-- arg=[RESULT_VARIABLE]
-- arg=[CMAKE_C_COMPILER_ID_RESULT]
But confusion continues. I changed cc.rex to echo its arguments on entry and
its return code on exit to a log, and:
GOOD:
dcc.exe -o CMakeFiles/cmTryCompileExec.dir/testCCompiler.c.o -c
C:/SVN/zFPE/CMakeFiles/CMakeTmp/testCCompiler.c

BAD:
dcc.exe CMakeCCompilerId.c
So arguably this is a bug in my cc.rex, in that it's not noticing the missing
arguments. But of course, "it worked before". Also note that cc.rex *never gets
invoked against CMakeCCompilerId* in the GOOD case.
The more I look at this, the less I understand it...

I'm confused because neither of your examples has the semicolon, but what we
need is:
"regina.exe" "cc.rex" "dcc.exe" "CMakeCCompilerId.c"
But it sounds like you're saying that we're not actually getting invoked as:
cc.rex;dcc.exe CMakeCCompilerId.c
The problem is, I can't tell what we ARE getting invoked as. The symptoms match
regina being invoked with no operands, but I can't seem to prove that.
If I run with --trace and --debug-output, the last of the output is:
C:/Program Files (x86)/CMake
2.8/share/cmake-2.8/Modules/CMakeDetermineCompilerId.cmake(97):
EXECUTE_PROCESS(COMMAND ${CMAKE_${lang}_COMPILER} ${CMAKE_${lang}_
COMPILER_ID_ARG1} ${CMAKE_${lang}_COMPILER_ID_FLAGS_LIST} ${testflags} ${src}
WORKING_DIRECTORY ${CMAKE_${lang}_COMPILER_ID_DIR} OUTPUT_VARIABLE
CMAKE_${lang}_C
OMPILER_ID_OUTPUT ERROR_VARIABLE CMAKE_${lang}_COMPILER_ID_OUTPUT
RESULT_VARIABLE CMAKE_${lang}_COMPILER_ID_RESULT )
Called from: [2] C:/Program Files (x86)/CMake
2.8/share/cmake-2.8/Modules/CMakeDetermineCCompiler.cmake
[1] C:/SVN/zFPE/CMakeLists.txt
Does that tell us anything?

I did not notice previously that the reported ; is coming from a message()
command in a string and not a real command line that is invoked. The
2.8.1 output line misrepresents the actual command that is running.
What you mean by:
> SET(CMAKE_C_COMPILER "regina.exe" "cc.rex dcc.exe")
> SET(CMAKE_CXX_COMPILER "regina.exe" "cc.rex dcxx.exe")
is that you want the compiler to be invoked as
"regina.exe" "cc.rex dcc.exe" "CMakeCCompilerId.c"
where the second piece puts both files in a *single* argument, right?
Much of the discussion in this thread made it appear that you wanted
"regina.exe" "cc.rex" "dcc.exe" "CMakeCCompilerId.c"
but that is what the above-mentioned execute_process command ends up
running in 2.8.6 and causing the hang.
Correct?
