Hello,
-I think the dll was not created becase the libtool had undefined 
symbols, so it just made the static lib.
-I saw the following from the GMP documentation
"MINGW uses the C runtime library `msvcrt.dll' for I/O, so applications 
wanting to use the GMP I/O routines must be compiled with `cl /MD' to do 
the same. If one of the other C runtime library choices provided by MS C 
is desired then the suggestion is to use the GMP string functions and 
confine I/O to the application. "
Could this be the reason for the undefined references?  If so how do I 
"complie with the `cl /MD`"?  Do I have to use ./configure CFLAGS=cl /MD?

Attempts:
$ ./configure --disable-shared --enable-static --enable-cxx > 
/home/dan/config.log
$ make > /home/dan/make.log
libtool: link: warning: undefined symbols not allowed in 
athlon-pc-mingw32 shared libraries
libtool: link: warning: undefined symbols not allowed in 
athlon-pc-mingw32 shared libraries

$ ./configure CFLAGS="cl /MD" --disable-shared --enable-static 
--enable-cxx > /
home/dan/config_flags.log
configure: error: could not find a working compiler, see config.log for 
details

$ ./configure CFLAGS=cl/MD --disable-shared --enable-static --enable-cxx 
 > /hom
e/dan/config_flags.log
configure: error: could not find a working compiler, see config.log for 
details

$ ./configure CFLAGS='cl /MD' --disable-shared --enable-static 
--enable-cxx > /
home/dan/config_flags.log
configure: error: could not find a working compiler, see config.log for 
details

$ ./configure CFLAGS=cl /MD --disable-shared --enable-static 
--enable-cxx > /ho
me/dan/config_flags.log

Thanks,
