Comment 1 Fujii Hironori 2020-01-16 22:49:09 PST 
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

Cygwin Perl

$ perl -e 'use Cwd; print Cwd::realpath("")."\n"'
: No such file or directory at -e line 1.

Linux Perl

$ perl -e 'use Cwd; print Cwd::realpath("")."\n"'

  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. 🤞

r254954 landed Bug 206407 change.
I'll keep eyes on AppleWin EWS bots for a few days.
