Subject: Name of cross-reference file for C++ in gcc-2.95 for DJGPP

By default C++ compiler generates name of cross-reference output
(option -fxref) by adding '.' before filename and appending .gxref
after it. That of course is invalid name for plain MS-DOS.

So below is patch for gcc/cnfig/i386/xm-djgpp.h which changes that.
I haven't tested it yet. Only question is about the extension of file
we should use. Perhaps it's better to fit extension in 3 letters.
