Re: Grep --directories option

[Alfred M. Szmidt]

   You are wrong.  Obviously such a test can not be run when cross
   compiling, but that is true for all tests where you need to run a
   program (note that the above is meant as an actual C program doing
   a mkdir() and a read()).

   And when cross compiling, either the user has to specify the test
   result in a config cache, or grep needs to rely on host_os to
   determine the default for known systems.

Anything that requires someone to make an config.cache with specific
options is wrong.  As for relying on host_os, that might be OK, but I
still think that just reverting this to the way grep-2.4.x was is
better.
