Pierre,

The problem seems to come from the fact that we do not detect how to
generate the assembly code for our atomic operations. As a result we fall
back on the gcc mode for 32 bits architectures.

Here is the corresponding output from the configure script:

checking if cc supports GCC inline assembly... no
checking if cc supports DEC inline assembly... no
checking if cc supports XLC inline assembly... no
checking if CC supports GCC inline assembly... no
checking if CC supports DEC inline assembly... no
checking if CC supports XLC inline assembly... no
checking for assembly format... default-.text-.globl-:--.L-_at_-1-0-1-1
checking for asssembly architecture... IA32

But there is something strange with the system you're compiling on. The
size of a C pointer is detected as 8 bytes, so this system is running in
64 bits mode. However, configure report it as a i386-pc-solaris2.10
(basically a 32 bits mode).

Give us one or two days to find a fix.

Thanks,
  george.
