Subject: Re:  configure produces strange gmp, mpfr lib directories.

There are multiple logs --

1)  I switched to static libraries, but tried both static and shared 
(the static libs are more standard, and less likely to choke libtool -- 
if its having problems).
2)  I built gmp and mpfr separately (I've had successful builds on both 
Cygwin and OS X in that config), and I've used the mpfr that comes with 
the gmp distribution.  When I hack the Makefile to correct the complaint 
I'm writing about below, I still have problems resolving symbols.  
HOWEVER: the issue I'm looking at here is something I have been able to 
isolate, and it looks like a good place to start.

configure: error: GMP with MPFR support is required to build fortran
watplatt@haplo.watson.ibm.com:/geno4/watplatt/gcc/gcc-4.1.1.build $

When I switch the -with-gmp... to /usr/local/lib, the script builds, but 
the Makefile contains

# Where to find GMP
HOST_GMPLIBS = -L/usr/local/lib/lib -L/usr/local/lib/lib -lmpfr -lgmp
HOST_GMPINC = -I/usr/local/lib/include -I/usr/local/lib/include

It should say /usr/local/include, and /usr/local/lib.  The libs are there:

ls -CF /usr/local/lib/*gmp*
/usr/local/lib/libgmp.a    /usr/local/lib/libgmp.la*
watplatt@haplo.watson.ibm.com:/geno4/watplatt/gcc/gcc-4.1.1.build $

 ls -CF /usr/local/lib/*mpfr*
/usr/local/lib/libmpfr.a    /usr/local/lib/libmpfr.la*
watplatt@haplo.watson.ibm.com:/geno4/watplatt/gcc/gcc-4.1.1.build $

Without correcting the /usr/local/lib/lib reference in the make file, I get:

-Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros

If I try to fix the /usr/local/lib/lib reference, there are yet more

Explicit declarations of the libraries I want to load 
(/usr/local/lib/libgmp.a, for example) does not improve things.

But then, there's things in this configuration about which I am not sure 
what's going on -- where some environment vars are getting set, which 
ones which makefiles are seeing, etc.

WHICH logs do you want to see? which runs are most interesting to you?
