-# It messes up all kinds of things:
-# For 6.0 and 6.1, expand_env() will not work correctly.
-# For 6.2 and 6.3 the call to free_line in u_freeentry is wrong.
-# The "read.me" file for version 6.56 includes a remark about a fix for the

-# You should use Manx Aztec C whenever possible, because it has been tested.

-# The prototypes from Manx and SAS are incompatible. If the prototypes
-# were generated by Manx, first do "touch *.c; make proto" before "make".
-# The prototypes generated on Unix work for both.
