I don't know where you got that idea.  It's perfectly fine to use w32api
functions in combination with cygwin/posix ones -- how do you think
mintty works? -- although you do need to be careful mixing stuff like
posix select() and w32 WaitFor*().

          ^^^^^^^^^^^^^^^^^
Here's your problem: binutils and gcc don't support compiling "in the
source tree".  You need to create a separate, empty build directory
*outside* the src directory, and run configure/make in there.

Dunno about your dmake problems, someone else will have to address that.
