+Changes made:
+
+    Renamed "regexp.h" to "tptregexp.h" to avoid conflicts with systems that
+    have a /usr/include/regexp.h.  Changed the *.c files in the appropriate
+    places.
+
+    Renamed these routines:
+	regcomp()  -> tpt_regcomp()
+	regexec()  -> tpt_regexec()
+	regsub()   -> tpt_regsub()
+	regerror() -> tpt_regerror()
+    This is to avoid conflicts in the standard C library.
+
+    In Makefile - wrote "all" and "install" targets.  Changed "regexp.h"
+    to "tptregexp.h", as appropriate.
+
+    In regexp.c - added #include <string.h> to keep compiler happy.
