AFAIK, there are, but you've got to search a little.

Stricter checking for \-escapes was added at some point. The
shell-escape routine of swipl-ld changes $ into \$, which is not a good
idea on Windows. I pushed a number of patches to fix this, changing
$welcome to the more traditional version/0 and version/1 predicates
that avoid the need for quoting altogether and fixing the quote routine.

You can simply fix this by adding "-g true" to suppress the
initialization goal.
