OK, I'm taking this.

There are dozens of AC_TRY_COMPILE invocations in gnulib's macros.
Nobody who uses "autoconf -W obsolete" complained about them so far,
and probably noone will until autoconf 3.0 really drops this macro or
emit serious warnings for its use.

I don't see why I should be the first one to engage in AC_TRY_COMPILE's
elimination.

Thanks, yes they are documented now. (Hope they won't be withdrawn before
autoconf-2.60 :-).) I applied this as well.
