The point is that we don't want messaging for some tests. Most people
find the 'configure' output already long enough.
The underlying problem in Autoconf is the following: There is a macro
AC_CACHE_CHECK that does messaging, and a macro AC_CACHE_VAL whose
main purpose is to make a cache lookup, not messaging, but it
nevertheless outputs '(cached)' strings occasionally.
Please fix this correctly
- either by having AC_CACHE_VAL set some shell variable that
AC_CACHE_CHECK will inspect after executing AC_CACHE_VAL,
- or by introducing a macro that is like AC_CACHE_VAL but produces
no spurious output.
Then AC_CACHE_VAL or the other macro is properly silent, and then no
gl_CACHE_VAL_SILENT will be needed any more.
