--enable-mpfr on Windows 2000

[Sisyphus]

Hi,

Running MSYS-1.0.8 and MinGW-2.0.0-3 on Win 2k.
Ran:
./configure --disable-static --enable-shared --enable-mpfr

When I try to build apps using mpfr I get "undefined references" to 
"__gmpn_copyd" and "__gmpn_copyi". They are the *only* undefined 
references I get.

Thinking that perhaps I was doing something dumb (rather than it being a 
bug), I posted to the gmp-discuss list.

Kevin Ryde had this to say:
--quote--
"I think for all x86s those are functions (rather than inlines).  You
should find mpn/copyd.lo and mpn/copyi.lo, and they should be going
into libgmp (I forget what tool reads a dll symbol list).

I think libtool asks for all symbols exported by default.  If that's
not working maybe adding __GMP_DECLSPEC to the prototypes in
gmp-impl.h will help."
--endquote--

I followed his suggestion re adding '__GMP_DECLSPEC' to the 2 prototypes 
and that works nicely.

I've since tried building with the latest MSYS (version 1.0.10-rc-3) and 
the latest MinGW (version 3.1.0-1). Exactly the same problem occurs. (I 
presume the same fix would also apply but I didn't check that.)

Cheers,
Rob
