# Default on 3.2v4 is to use static link (dynamic loading unsupported).
# Default on 3.2v5 is to use dynamic loading.
# To use static linkink instead, use to sh Configure -Dusedl=n
#
# Warning: - to use dynamic loading with gcc, you need gcc 2.8.0 or later
# ******** - to compile with older releases of gcc, use Configure -Dusedl=n
#            or it wont compile properly
#
###############################################################
# NOTES:
# -----
#
# I Have removed inclusion of ODBM_File for OSR5
# because it core dumps and make tests fails.
#
# Support for icc compiler has been removed, because it 'breaks'
# a lot of code :-(
#
# It's *always* a good idea to first make a static link to be sure to
# have all symbols resolved with the current choice of libraries, since
# with dynamic linking, unresolved symbols are allowed an will be detected
# only at runtime (when you try to load the module or worse, when you call
# the symbol)
#
# The best choice of compiler on OSR 5 (3.2v5.*) seems to be gcc >= 2.8.0:
# -You cannot optimize with genuine sco cc (miniperl core dumps),
#  so Perl is faster if compiled with gcc.
# -Even optimized for speed, gcc generated code is smaller (!!!)
# -gcc is free
# -I use ld to link which is distributed with the core OS distribution, so you
#  don't need to buy the development kit, just find someone kind enough to
#  give you a binary release of gcc.
