You could just as well have a look at your mails.  I already explained you
how to re-activate the old names.

I promise that this macro will never make it back again into stdio.h.

As for "iswhite" simply use the correct macros.  Either "isspace" (returns
true for any whitespace character) or "isblank" (returns true for blank
characters, i. e. space and horizontal tab).  The latter is a GNU
extension.  You therefore have to give your gcc the option "-D_GNU_SOURCE"
to use this macro.

The internal library functions "_write_utmp" and "_write_wtmp" have been
removed (ding, dong, you were asking for a standard compliant utmp/wtmp
handling).  As a quick replacement you can simply use "login ()" (see the
manpage login(2) on another system).  But there are also lastlog/faillog
entries to be written if applicable.  This will cause some headaches but
I'm in contact with Christian Felsch about this.

If you don't want to fiddle around with "login()" simply 

	ar x /usr/lib/oldlib/libc.a utmp.o
	ar r /usr/lib/libc.a utmp.o
	ranlib /usr/lib/libc.a

(extract "utmp.o" from an old MiNTLib, stuff it into your new one and run
ranlib over the modified lib).

Ciao
