AC_C_TYPEOF documentation

[Bruno Haible]

Hi,

The AC_C_TYPEOF documentation makes it sounds as if, in order to use
'typeof', a program needs to do

    #if HAVE_TYPEOF || defined typeof

But actually, looking at the implementation in c.m4, a

    #if HAVE_TYPEOF

is enough. Here is a documentation fix.

  If the C compiler supports GCC's @code{typeof} syntax, define
  @code{HAVE_TYPEOF}.  If the support is available only via a different
  spelling of the keyword (e.g., @code{__typeof__}), define @code{typeof}
! to that spelling.
