+* Yacc.c: CPP Macros
+
+Do some people use YYPURE, YYLSP_NEEDED like we do in the test suite?
+They should not: it is not documented.  But if they need to, let's
+find something clean (not like YYLSP_NEEDED...).

+* readpipe
+
+It should be replaced to avoid tmp files and to improve portability.
+Also, as it is it does not call error () when execve fails, and
+therefore, running M4='m4 --version' bison will silently fail instead
+of:
+
+	bison: cannot run m4 --version: No such file or directory

+BTW: I would really like to be able to pass arguments to m4...
