I mean to be exactly symetric, REGFIX should always be defined.

in enc-option.patch-to-7.5 :

+dump_int(enc_option);
+if enc_option then
+begin
+  dump_things(xord[0], 256);
+  dump_things(xchr[0], 256);
+  dump_things(xprn[0], 256);
+  dump_things(mubyte_read[0], 256);
+  dump_things(mubyte_write[0], 256);
+  dump_things(mubyte_cswrite[0], 128);
+  print (" encTeX data dumped");
+end

If you dump a boolean using dump_int, it will be cast to an int. If you
undump it without REGFIX defined, then it will be undumped as a boolean,
at least on my machine/compiler.
