perl@​7369 fails t/lib/st-lock.t under djgpp-dos with this error​:

lib/st-lock.........can't get exclusive lock on store​: Function not
implemented (ENOSYS) at lib/st-lock.t line 41
lib/st-lock.........dubious
  Test returned status 255 (wstat 65280, 0xff00)
DIED. FAILED tests 1-5
  Failed 5/5 tests, 0.00% okay

The cause is that the DJGPP libc "fcntl" function does not implement
F_SETLK/W functions, though the constants are defined. Since we also
do not have "flock", perl tries to emulate "flock" with "fcntl", and
fails.

A patch is not imminent, but the djgpp-workers will be contacted for
suggestions. DJGPP does have "lock" and "unlock" functions, but
these are only for "regions" of a file, and will not work in plain
DOS unless SHARE.EXE (a DOS TSR for sharing files) is loaded.

In the meantime, can the extension "Storable" be excluded from a
default DJGPP "configure -des" without serious repercussions? IOW, if
the extension "Storable" is not made, what breaks or fails to run that
DJGPP users might want to use?

Any input on this subject would be appreciated.
