Summary: msys attempts PATH translation of semi-POSIX paths

Initial Comment:
The original problem raised by Charlie Savage on the
mingw-users list was that msys mangles the following
command:

$ mingw_echo.exe --with-ldflags="-L/usr/local/lib
-LD:/msys/1.0/local/lib"
arg[1] = --with-ldflags=-Ld:\GNU\local\lib
-LD;D:\GNU\msys\msys\1.0\local\lib

The path 'D:/msys/1.0/local/lib' is interpreted as a
Unix style PATH containing D and /msys/1.0/local/lib;
this is converted into a DOS style PATH separated by a
semi-colon, and the following translations also occur:

D -> D
/msys -> D:\GNU\msys

Workaround details
==================

the simplest workaround is to only use Unix paths, but
there are a few more:

1. reversing the ordering works around the problem

$ /bin/mingw_echo.exe
--with-ldflags="-LD:\msys\1.0\local\lib -L/usr/local/lib"
arg[1] = --with-ldflags=-LD:\msys\1.0\local\lib
-L/usr/local/lib

2. using backslashes in the DOS path also works

$ /bin/mingw_echo.exe --with-ldflags="-L/usr/local/lib
-LD:\msys\1.0\local\lib"
arg[1] = --with-ldflags=-L/usr/local/lib
-LD:/msys/1.0/local/lib

Cause
=====

The problem appears to be triggered by a space in the
argument.

$ mingw_echo.exe "D:/"
arg[1] = D:/

(works)

zeroj@PIONEER ~
$ mingw_echo.exe " D:/"
arg[1] =  D;D:\GNU\msys

(fails)

Reducing priority because many workarounds exist.
