it got omitted due to an error in the clisp Makefile.

+libsigsegv is a library for handling page faults in user mode. A page fault
+occurs when a program tries to access to a region of memory that is
+currently not available.
+
+NOTE:
+This overwrites /usr/include/sigsegv.h from clisp (included in Slackware),
+but that should not cause any problems, as they are exactly the same.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
