In which of these directories do you have bzip2.exe?

This doesn't tell anything, since you obviously typed these commands
from some Unixy shell, and the resulting file name isn't related to
any of the directories shown in PATH above.  A native build of Emacs
doesn't know about all the "mounted" directories created by MSYS and
Cygwin, it searches only the native Windows PATH.  You should make
sure your bzip2.exe is found in one of those directories, or add its
directory to system-wide PATH before starting Emacs.
