+# 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

+# 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 developement kit, just find someone kind enough to
+#  give you a binary release of gcc.
