+# This is a makefile for UNIX
+
+# CHANGES MADE TO THIS FILE UNDER RSAREF license clause 1(c):
+#
+#  For the MIT PGP 2.6 distribution, this file was modified to permit
+#  replacement of the NN_ModExp routine by an equivalent routine
+#  contained in the PGP 2.6 sources.  To enable this change, an #ifdef
+#  was added to the nn.c file (search for #ifndef USEMPILIB
+#  below).  RSAREF *must* be compiled with USEMPILIB defined for this
+#  change to occur.
+#
+#  This makefile was changed to use GCC and to define USEMPILIB
+#  Change made May 21, 1994.
