 # Find C compiler
 # ---------------
 
+# If a non-executable a.out is present (e.g. created by GNU as above even if
+# invoked with -v only), the IRIX 6 native ld just overwrites the existing
+# file, even when creating an executable, so an execution test fails.
+# Remove possible default executable files to avoid this.

+# FIXME: This really belongs into AC_PROG_CC and can be removed once
+# Autoconf includes it.
