+# - warnings turned off (-n32 messages):
+# 1116 - non-void function should return a value
+# 1048 - cast between pointer-to-object and pointer-to-function
+# 1042 - operand types are incompatible

+# Tweaked by Chip Salzenberg <chip@perl.com> on 5/13/97

+# Don't bother with -n32 unless you have the 7.1 or later compilers.
+# But there's no quick and light-weight way to check in 6.2.
+
+# NOTE: some IRIX cc versions, e.g. 7.3.1.1m (try cc -version) have
+# been known to have issues (coredumps) when compiling perl.c.
