Agreed. Autoconf generates a config.h that encourages #ifdef/#ifndef.
And then it promotes the use of #if. I recall discussions about this
in the autoconf list years ago, and there was a conscious decision to
replace most uses of #ifdef with #if in the documentation, but I can't
find any wording that explicitly recommends the use of #if over
#ifdef. Oh well...
We should just use that style throughout.
And perhaps suggest that autoconf adds a note about this and reverts
to ifdef to avoid such warnings.
