I cannot see any way to "fix" MinGW so that a user using a Windows 
command shell can invoke GCC with a long command line; by the time GCC 
is invoked, the command has already been truncated.  That's why most 
(all?) compilers for Windows have "@file" or equivalent.

The obvious suggestion is that the user should use a "real" shell. 
However, since the user is often not invoking the compiler directly, but 
is instead using an IDE or some make program, that's not a practical option.
