This would be welcome. Something like this (untested)? *** autoheader.m4.bak 2005-05-14 09:00:39.000000000 +0200 --- autoheader.m4 2006-07-04 02:08:30.000000000 +0200 *************** *** 67,74 **** # # Quote for Perl '' strings, which are those used by Autoheader. m4_define([AH_VERBATIM], ! [AS_LITERAL_IF([$1], ! [AH_OUTPUT([$1], AS_ESCAPE([[$2]], [\\'']))]) ]) --- 67,76 ---- # # Quote for Perl '' strings, which are those used by Autoheader. m4_define([AH_VERBATIM], ! [m4_ifval([$1], !
