flock module

[Eric Gallager]

Recently in GCC bug 66005, there was discussion about possible need
for flock support in the libgomp testsuite:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66005
I brought up gnulib's flock module, however, there was some concern
about how its documentation says, "[T]he replacement function does not
really work; it exhibits test failures."
https://www.gnu.org/software/gnulib/manual/html_node/flock.html
Do these test failures still occur? What needs to be done to get the
replacement function working properly?
(Note that the libgomp testsuite will be going with a different
workaround instead, but I still think it would be worthwhile to get
the gnulib module working properly, even if GCC isn't going to use it)
Thanks,
Eric Gallager
