211     ## supported by the other compilers which use the 'gcc' depmode.

232     ## typically no way to rebuild the header). We avoid this by adding
233     ## dummy dependencies for each header file. Too bad gcc doesn't do
234     ## this for us directly.

236 michael 5052 ## that the space means something, we add a space to the output as
