Autoconf on Solaris 10 64-bit Sparcv9

[Chino Aureus]

Hi,

I 'm currently porting my application (shared library actually) to 64-bit.
I'm using autotools (i.e. automake, autoconf, etc...).

In Solaris 10, I was able to compile (doing ./configure, make and make
install) my shared library ok but as 32-bit.  However, since I want this to
be compiled as 64-bit, I added the -m64 and -Wl,-64 options to CPPFLAGS and
LDFLAGS respectively.  When I compile:

1. Generated objects files.. i.e. *.o  are in 64-bit
2. When It tries to link all the objects files, It seems it is trying to
generated a 32-bit library file (.so):
ERROR...........
ld: warning: option -o appears more than once, first setting taken
ld: fatal: file .libs/libNecropolis_la-Logger.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to
.libs/libNecropolis.so.1.

Please help, I think I'm missing something.

Below is my Makefile.am
