Package: gcc-4.2
Version: 4.2-20070528-1
Severity: wishlist
GCC 4.2 has partial support for decimal floating-point types (DFP):
http://gcc.gnu.org/onlinedocs/gcc/Decimal-Float.html
But it seems that this is not enabled by default. I think that gcc
should be built with --enable-decimal-float to get decimal float
support. Even if the API can change, users still have the choice
to use decimal floating-point types or not. So, there should be
no drawback.

see http://gcc.gnu.org/ml/gcc/2007-06/msg00080.html
"it's only supported for powerpc*-linux and x86*-linux"
"doesn't really work for x86*-linux unitl ... fixed a bunch of
back-end/middle-end bugs in 4.3"
already enabled for powerpc, enabled for i386 and amd64 in
gcc-snapshot. keep it disabled in gcc-4.2 for i386 and amd64.
