Re: recommending AC_SYS_YEAR2038_REQUIRED ?

[Bruno Haible]

Paul,

Here's a suggestion for a compromise.

Recall that the macro AC_SYS_YEAR2038_REQUIRED is like AC_SYS_YEAR2038,
with two modifications:
  - It causes configure to fail if a large 'time_t' is unavailable,
  - It removes the configure option --disable-year2038.

How about a middle ground between the two macros? A macro, say
AC_SYS_YEAR2038_UNLESS_OPT_OUT (*), that
  - like AC_SYS_YEAR2038, has the option --disable-year2038,
  - like AC_SYS_YEAR2038_REQUIRED, fails if a large 'time_t' is
    unavailable and --disable-year2038 was not specified.

It would force the packager to pass --disable-year2038 if he
accepts the year-2038 problems.

It would not require additional documentation.

That would be OK with me.

Would it be OK with you?
