local macro problem

[Harlan Stenn]

I'm looking for a way to define unsigned-long constants.  I have to support
K&R and Ansi C compilers.

I have been using:

acconfig.h:
#undef ULONG_CONST

acinclude.m4:
AC_DEFUN(hs_ULONG_CONST,
[ AC_EGREP_CPP(Circus,
 [#define ACAT(a,b)a ## b
ACAT(Cir,cus)
], AC_DEFINE([ULONG_CONST(a)], [a ## UL]),
    AC_EGREP_CPP(Reiser,
[#define RCAT(a,b)a/**/b
RCAT(Rei,ser)
], AC_DEFINE([ULONG_CONST(a)], [a/**/L]),
    AC_MSG_ERROR([How do we create an unsigned long constant?])))])

and I'm trying to lose the entry in acconfig.h and use the "template" form
of AC_DEFINE.

The bad news is that I apparently haven't gotten the quoting right.

If I just add the template to AC_DEFINE(ULONG_CONST...) autosomething goes
insane becuase it's under-quoted.

If I add [] around the AC_DEFINE(ULONG_CONST...) bit then auto* is happy but
the resulting entry in config.h.in is Wrong.

Anybody have something I can swipe, or ideas on what I'm doing wrong?
