[issue15963] Improve ./configure's support for 32/64-bit debug|release|profiled builds w/ vendor (non-gcc) compilers on proprietary UNIX systems (Solaris/HP-UX/AIX et al).

[Stefan Krah]

Stefan Krah added the comment:

I'm glad I found this. Without the long incantation _decimal is
seriously miscompiled on SPARC/Solaris 10/Sun Studio 12.3. I was
using just ...

  ./configure --without-gcc CFLAGS=-m64 LDFLAGS=-m64

..., and that seems to trigger an optimizer bug that produces
different output for _mpd_div_words_r() when called with exactly
the same input at different locations.


The line that Trent gave appears to work.
