[erlang-questions] failed to build docs on windows

[Michael Stellar]

When i am attempting build docs with make docs in windows, it seems
escript failed to translate unix based path in cygwin, the make docs
return this error

PATH=/home/Michael/otp_src_R14B04/bin:${PATH} escript
/home/Michael/otp_src_R14B04/lib/erl_docgen/priv/bin/xref_mod_app.escript
-topdir /home/Michael/otp_src_R14B04 -outfile
/home/Michael/otp_src_R14B04/make/win32/mod2app.xml
Makefile:416: recipe for target `mod2app' failed

I already have erlang, fop, xsltproc in my path, the erlang binaries
already successfully built in this cygwin setup which is based on the
guide, does it's not really possible to build docs on windows ?.
