Well, I did say "at least"...

Actually, I meant for values to (tentatively) add to CFLAGS with -I before
invoking AC_CHECK_HEADER() if "test -d DIR" (or "test -f DIR/pcre.h")
is true.  So, /usr/include does not need to be added explicitly at that
step, since the preprocessor will always look there anyway.

I made one mistake above:  it should be $prefix/include/pcre instead
of what I wrote.  Plain $prefix/include could be (tentatively) added as
well, if $prefix differs from /usr (gcc also checks in /usr/local/include
by default, but maybe not other C compilers).
