The default m4 quote characters: `QUOTE' are troublesome, because ` is fairly likely to pop up in a shell script (if not for a subshell, because it is a useful character in comments and user-facing messages). So, this changes it to [[[QUOTE]]], as it is unlikely to see three braces together like that, let alone in unbalanced sets. --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Makefile b/Makefile index f4a00ba..d5f6ad7 100644 --- a/Makefile +++ b/Makefile @@ -74,7 +74,7 @@ edit = sed -e "s|@pkgdatadir[@]|$(DESTDIR)$(PREFIX)/share/devtools|g" %: %.in Makefile lib/common.sh @echo "GEN $@" @$(RM) "$@" - @m4 -P $@.in | $(edit) >$@ + @{ echo -n 'm4_changequote([[[,]]])'; cat $@.in; } | m4 -P | $(edit) >$@ @chmod a-w "$@" @chmod +x "$@" @bash -O extglob -n "$@" -- 2.12.2
