O_EXLOCK is a BSD feature, and Cygwin tries to emulate Linux, not BSD.
Minimal testing tells me you can use Cygwin's nonstandard
F_LCK_MANDATORY feature from Perl. This script, foo.pl, doesn't die:
sysopen my $fh, "foo.pl", 0600, O_RDONLY or die "sysopen: $!\n";
fcntl $fh, 0x99, 1 or die "fcntl: $!\n";
Whether it actually does what you expect is a different question.
