According to the FAQ entry, the Cygnus version of make runs in two modes:
Unix and Windows. In Windows mode, make use the Windows command shell  to
launch applications. Thus, in Jin's case, assuming he was running make in
Windows mode (the default), bash launches make which then uses cmd to
launch javac. javac sends it standard out to the Windows command shell and
then make tries forward it to a command shell that it assumes is also cmd
(because it is running in Windows mode) but which is really bash. The
incompatibility between Windows and Unix SIO  seems a reasonable
explanation to me for Jin's problem.

I may be wrong but certainly it wouldn't hurt for Jin to try to run Cygnus
make in Unix mode if he intends to run it under bash.

But not to BEGIN a path as in Jin's example.
