23# Warning: - to use dynamic loading with gcc, you need gcc 2.8.0 or later

28# NOTES:
29# -----
30#
31# I Have removed inclusion of ODBM_File for OSR5
32# because it core dumps and make tests fails.
33#
34# Support for icc compiler has been removed, because it 'breaks'
35# a lot of code :-(
36#
37# It's *always* a good idea to first make a static link to be sure to
38# have all symbols resolved with the current choice of libraries, since
39# with dynamic linking, unresolved symbols are allowed an will be detected
40# only at runtime (when you try to load the module or worse, when you call
41# the symbol)
42#
43# The best choice of compiler on OSR 5 (3.2v5.*) seems to be gcc >= 2.8.0:
44# -You cannot optimize with genuine sco cc (miniperl core dumps),
45# so Perl is faster if compiled with gcc.
46# -Even optimized for speed, gcc generated code is smaller (!!!)
47# -gcc is free
48# -I use ld to link which is distributed with the core OS distribution, so you
49# don't need to buy the developement kit, just find someone kind enough to
50# give you a binary release of gcc.
