No John, I do not use Visual Studio IDE. I just do 'cd math/test' and
launch simple bjam command there:

  bjam --disable-icu --toolset=sun_cpp11 -d+2 -j4 link=shared
runtime-link=shared variant=release threading=multi

After that I see that bjam's logfile contains configuration checks with
wrong "yes" labels.

Performing configuration checks
     - has_ntl_rr builds : yes
     - has_mpfr_class builds : yes
     - has_mpreal builds : yes
     - has_e_float builds : yes
     - has_gmpxx builds : yes
     - 128-bit floatmax_t : yes

which I guess, triggers "Error: Could not open include file ..." messages.

Probably all those wrong labels have been generated inside
build/src/build/configure.jam, but how exactly configuration checks
work in this case is beyond my understanding.
