------docs/STANDALONE-TOOLCHAIN.htm--------------....5/ Warnings and Limitations:
5.1/ Windows support:
The Windows binaries do *not* depend on Cygwin. The good news is that they
are thus faster, the bad news is that they do not understand the Cygwin
path specification like /cygdrive/c/foo/bar (instead of C:/foo/bar).
The NDK build system ensures that all paths passed to the compiler from Cygwin
are automatically translated, and deals with other horrors for you. If you have
a custom build system, you may need to deal with the problem yourself.
NOTE: There is no plan to support Cygwin / MSys at the moment, but
contributions are welcome. Contact the android-ndk forum for details
