update minmax.m4

[Stepan Kasal]

Hello Bruno.

I think it's time to re-submit my patch to minmax.m4.
A new version of the patch is attached to this mail.

Again, it features:

> - use m4_pushdef/m4_popdef instead of define/undefine

As I explained before, you cannot inadvertently undefine([HEADER]).

> - avoid the obsoleted AC_TRY_COMPILE

Some people run "autoconf -W obsolete", and the macros from gnulib
shouldn't spoil it.

> - use AS_TR_* instead of raw m4_translit


Do you see any problem with this patch?  All used macros are now documented.

Have a nice day,
        Stepan
