Indeed.  We do not re-document all compilers and their options'
suitability for GMP.

  Note: This option (which covers much more than empty translation units)
  can be useful for his own programs and possibly other programs, and
  might been enabled globally as a consequence.

There are many options which break programs, and if people play with
these options, they are presumably prepared to deal with the fallout.

  Not hypothetical, as I've explained just above. The development time
  of the other users is valuable too.

Absolutely!  That's why we spend so much time on actual portability and
have one of the largest test setups in the FOSS world.
