Hi Jan, DJ,

Could you please clarify your positions about the problem and suggested patch?
Attaching the patch for references.

TBD. Here is not complete list of problems in gcc-based cross development when
build platform uses DOS-style FS and target platform uses Linux-style FS:
1. If you do crossbuild with gcov support, binaries refer gcda files like C:\Myproject\Mydir\Myobj.gcda.
After run on Linux files with names  like "C:\Myproject\Mydir\Myobj.gcda" are created.
No any directory tree;
2. Current filename_cmp fails to compare c:/a/b/.. and c:/a;
3. Include files names on DOS-style FS quite often become too long because of their 
"denormalization" after concatenation(i.e a/ + ../b becomes a/../b but may be used as b/);
4. The same (as 1.) problems appear in gdb during debug cross-built programs on Linux side.

Best regards
Vladimir
