+# - assumes 'cc -n32' by default
+# - tries to check for various compiler versions and do the right
+# thing when it can
+# - 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 assume 'cc -n32' if the n32 libm.so is missing
+
+# Threaded by Jarkko Hietaniemi <jhi@iki.fi> on 11/18/97
+# - POSIX threads knowledge by IRIX version
