That's related to tmp being underquoted, see the following even more reduced testcase AS_INIT m4_defun([AS_DOIT], [: $1]) m4_define([tmp], [AS_TR_SH(foo)]) AS_DOIT(tmp) => : # Sed expression to map a string onto a valid variable name. as_tr_sh="eval sed 'y%*+%pp%;s%^_$as_cr_alnum%_%g'" foo AS_INIT m4_defun([AS_DOIT], [: $1]) m4_define([tmp], [AS_TR_SH(foo)]) AS_DOIT([tmp]) => # Sed expression to map a string onto a valid variable name. as_tr_sh="eval sed 'y%*+%pp%;s%[^_$as_cr_alnum]%_%g'" : foo Paolo
