Re: mbsinit() not defined

[Stepan Kasal]

Dear autoconf wizards,

Ilya N. Golubev has reported a bug:

As Ilya has pointed out, the same problem was on Mon, 18 Jun 2001 reported
for gettext:
http://lists.gnu.org/archive/html/bug-gnu-utils/2001-06/msg00184.html

Bruno has accepted the proposed solution: #define mbsinit(ps) 1

Couldn't this become part of autoconf?  Perhaps the AC_FUNC_MBRTOWC macro
could make sure that mbsinit() is defined and provide the replacement
if it's needed.

Thank you in advance for clarification,
        Stepan Kasal
