Intel on Linux has the same issue:

jm_at_jm-laptop:~/boost/sandbox/math_toolkit/libs/math/build$ bjam intel
Error: ambiguity found when searching for best transformation
Trying to produce type 'CPP_PCH' from:
 -  { ../src/tr1/pch.hpp.HPP }
Generators that succeeded:
 -  pch.default-cpp-pch-generator
 -  intel-linux.compile.c++.pch
First generator produced:
Second generator produced:
 -  { intel-linux%intel-linux.compile.c++.pch-../src/tr1/pch.hpp.pch.CPP_PCH 
{ ../src/tr1/pch.hpp.HPP } }

Unfortunately the compiler appears not to imitate gcc's support, but instead 
uses a more Win32 like mechanism, there's a description here: 
http://www.nersc.gov/vendor_docs/intel/c_ug/lin1157.htm.  Likewise sun's 
compiler uses a similar mechansim:

If someone can suggest patches I can happily test them here.

Thanks, John.
