Initial testing didn't show any change (= still fails), but I have no
way to tell whether the fix above is already in the snapshot (dated June
25th), although the time stamps would seem to suggest it.
Just to be sure I've put up a new snapshot (regular, not gtk3)
today, and tested it on Windows 10. Here's my test script:
<hansl>
remove("c:\users\cottrell\print.out")
! "c:\users\cottrell\printarg.exe" "foo" >
"c:\users\cottrell\print.out"
eval readfile("c:\users\cottrell\print.out")
</hansl>
printarg.exe is a trivial C program which prints the argument it
received to stdout. The (redirected) output file is created OK.
