PCRE2 tests 24 and 25 do not explicitly set the glob escape character so right now test 24 fails on Windows. Test 25 passes because it does not use the escape syntax.
With the following line in testinput24 adjusted, it generates the expected results:
# Set the glob separator explicitly so that different OS defaults are not a
# problem. Then test various errors.
#pattern convert=glob,convert_glob_escape=\,convert_glob_separator=/
~~~~~~~~~~~~~~~~~~~~~
The same change should probably be applied to testinput25 in case escape syntax is used in the future.
