[PATCH] gdb/testsuite: make MSYS path normalization case-insensitive

[Oleg Tolmatcev]

When normalizing Unix-style paths for native MinGW hosts, compare
MSYS mount prefixes case-insensitively.

This avoids mis-normalizing paths like /C/... by failing to
match the /c mount point and then falling back to the root
mount instead.

I am dropping this patch. The solution is not to use upper case for
the drive letter when
changing the directory. I can not reproduce it if I do that.
