Unfortunately VC 6 is a very old compiler and has many bugs.  It lacks support 
for
many standard C++ features.  Therefore currently we don't have plan to support 
it. 
You are welcome to port google test to VC 6 yourself if you are interested.

Hi, I'm currently porting to VC6.

Try attached version(my personal build) if you are interested. VC6.dsp is a 
sample test program. Quite tiny, 
but it does compile and work.

It seems difficult for me to port perfectly, because VC6 provide quite poor 
support for C++ standard as Wan 
said, especially template which heavily used in gtest. But I will keep trying.

Currently, 287/292 test in gtest_unittest.cc(Tests for google test) passed.
