Giving "" to Cwd::realpath results different result on Cygwin Perl, Windows perl, Linux perl. perl -e 'use Cwd; print Cwd::realpath("")."\n"' Cygwin and Windows: An error occurs. "No such file or directory" Linux: It returns the current directory Bug #117944 for PathTools: realpath: different behavior on non-existent directory between Unix and Windows https://rt.cpan.org/Public/Bug/Display.html?id=117944

Bug 206407 – preprocess-idls.pl: CygwinPathIfNeeded should use Cygwin::win_to_posix_path instead of invoking cygpath I hope above change would happen to solve this issue. 🤞

This error still happened today. https://ews-build.webkit.org/#/builders/10/builds/4541 r254954 landed Bug 206407 change. I'll keep eyes on AppleWin EWS bots for a few days.
