[CMake] 64 bit windows: rsp file not employed in build.make

Hi,
I'm investigating a problem where on 64-bit Windows the generated build.make (NMake or NMake JOM) does not make use of response files. I have tried transplanting the settings file for the 32 bit platform and minimizing differences, but still I cannot get it to use rsp files. This is a problem because I can't create one of the static libraries, since the command line is too long. Except for the missing rsp mechanism, I'm also unsure why in one case the linking is done through link.exe and by lib in the other.
I've made sure to:
- use a fresh copy of cmake 2.8.2 on both machines
- not to mess with CMAKE_START_TEMP_FILE / CMAKE_END_TEMP_FILE
Is there a way to see how cmake arrives at a generated rule, perhaps as it is generating? Of course if you know anything that might cause this behavior I would be keen to learn it.
Thanks,
Arjen
