MinGW compatibility issues and solutions

[Christian Gudrian]

Symptoms:

I've encountered (and resolved) some problems building Emacs in an
MinGW environment under Windows XP.  Since I don't know if Emacs is
supposed to compile in such an environment at all this might not
actually a bug. :)

However this information might be useful for one or the other.

1. loaddefs.el does not get updated during the bootstrap process.

   Cause: GNU make's $(CURDIR) variable contains a path in MinGW
   format (e.g. /d/emacs/src/lisp).  Emacs expects a path in DOS
   format with backslashes replaced by slashes
   (e.g. d:/emacs/src/lisp).

   Resolution: when creating loaddefs.el only the filename is given.
   Since Emacs is called from within the destination directory,
   loaddefs.el is created in the proper location anyway.

2. Bootstrapping fails.

   Cause: byte compilation of lisp/url/vc-dav.el requires the
   documentation file DOC which is not present at that time of the
   build process.

   Resolution: before byte compiling the lisp files a preliminary DOC
   file is created by executing "make DOC" in the lib-src
   subdirectory.  The file is then copied to a location in which it is
   found during further compilation.

3. Calls to DOS style batch files fail.

   Cause: The MSYS shell is not capable of running DOS style batch
   files.

   Resolution: call the batch files via the command line interpreter
   cmd.

These are the changes I have made.  After these modifications Emacs
can be built from an MSYS shell prompt like this:

cmd /c configure.bat <options as required>
make bootstrap
make
make install
