What i have figured out so far is to list the default search path for gcc
in MinGW is to issue the command
gcc -### -o foo foo.c

This will produce the following:
$ gcc -### -o foo foo.c > /c/dev/gcc.txt
gcc.exe: error: foo.c: No such file or directory
Using built-in specs.
Target: i686-w64-mingw32
Configured with: ../../../src/gcc-4.9.1/configure --host=i686-w64-mingw32
--build=i686-w64-mingw32 --target=i686-w64-mingw32 --prefix=/mingw32

--with-tune=generic --with-libiconv --with-system-zlib
--enable-cloog-backend=isl --with-pkgversion='i686-posix-dwarf-rev0,
Built by MinGW-W64 project' --with-bugurl=
CFLAGS='-O2 -pipe
CXXFLAGS='-O2 -pipe
Thread model: posix
gcc version 4.9.1 (i686-posix-dwarf-rev0, Built by MinGW-W64 project)

So there right at the end is the "offending" path, some script that should
extract the -L paths, is bringing the ' character in, at the end of the
No where that script is and how to fix it i dont know.

Any suggestions?
