From b2621a91d70e5c86f4fbdce25eeb0f83df6645b6 Mon Sep 17 00:00:00 2001 From: Quinn Grier Date: Wed, 2 Nov 2016 00:58:25 -0500 Subject: [PATCH] doc: fix an infinitely recursing example The "single" macro infinitely recurses because its expansion contains the unquoted text " single-". The "double" macro almost has the same problem, but it is protected by extra quotes. In any case, the macro names being repeated in the macro definitions is not necessary. This commit changes the macro names to "foo" and "bar", which are taken from a very similar example in the GNU M4 1.4.17 manual.
