#     Exactly what is required beyond a standard OS/2 installation?
#     There are notes about "patched pdksh" I don't understand.

# Note that symbol extraction code gives wrong answers (sometimes?) on
# gethostent and setsid.

# Note that during the .obj compile you need to move the perl.dll file
# to LIBPATH :-(
