Though I originally thought that `#ifdef' should be used, when I came
to autoconf community, I heard this ``it is defined as `1', so
that you can use either `#if' or `#ifdef'.''
I cannot recall where i read this, nor I can recall any reason why
#if would be better.
If there is no reason against it, we might consider switching to
#ifdef. Paul, Ralf, what do you think?
And no, this issue is not regression: Autoconf 2.59 contains `#if HAVE'
22 times (not counting the docs), but NO occurence of `#ifdef HAVE'.
In current CVS, we have still 19 occurences of `#if HAVE' and only
7 occurences of `#ifdef HAVE' .
Have a nice day,
Stepan
