It is because of the quoting ambiguity (ambiguity to In general, always double-quote a macro argument that you wish to make a literal; that is, an argument in which m4 should not expand quotation or macro calls. Quote an argument only once to simply protect internal commas and unmatched parentheses. The node ``Autoconf Language'' describes this. It is possible to write a macro that will treat its arguments as literal; see the node `Quotation and Nested Macros'. Standard Autoconf macros do not do this, probably because it reduces flexibility, and writing configure.ac is easier if all macros quote arguments the same way. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
