ghc-split fails to quote path when used as regex

If the second argument to ghc/driver/split/ghc-split
contains
a backslash and a 'p', for example ...\pe..., the
script fails with an error message:

Can't find unicode character property definition via
main->e or e.pl at unicode/Is/e.pl line 0

The problem can be solved by a
$Tmp_prefix =~ s/\\/\\\\/g;
before it is used as a regexp around line 50 in ghc-split.
