[bug-gnulib] gnulib-tool treatment of gl_USE_SYSTEM_EXTENSIONS

[Oskar Liljeblad]

I noticed that gnulib-tool added gl_USE_SYSTEM_EXTENSIONS to gl_EARLY
despite the fact that no module used it. The problem seemed to stem
from these lines in gnulib-tool:

if grep gl_USE_SYSTEM_EXTENSIONS "$destdir"/$m4base/*.m4 > /dev/null; then
  echo "  gl_USE_SYSTEM_EXTENSIONS"
fi

Apparently gnulib.m4 was the only file that contains
gl_USE_SYSTEM_EXTENSIONS in the m4 directory, probably because some module
previously depened on it! Wouldn't it be better to add
"configure.ac-early" or something to module spec files
instead of testing for certain macros in gnulib-tool?
