Comment (by fano):

 I've tried to recompile gcc in the Haiku svn tree adding at configure
 --enable-decimal-float=true and I've done make... after a lot of checking
 I obtain:


 {{{
 checking if compiler knows _Decimal64... configure: error: Compiler
 doesn't know _Decimal64; try GCC >= 4.2, configured with --enable-decimal-
 float

 make[2]: *** [configure-stage1-mpfr] Error 1
 make[2]: Leaving directory
 `/boot/home/Desktop/HAIKUsrc/haiku/haiku/buildtools/gcc'
 make[1]: *** [stage1-bubble] Error 2
 make[1]: Leaving directory
 `/boot/home/Desktop/HAIKUsrc/haiku/haiku/buildtools/gcc'
 make: *** [all] Error 2
 }}}

 OK, the GCC that is compiling does not know _Decimal64, but it is for this
 I'm recompiling it!
 I do not understand to compile GCC with _Decimal64 sypport I've to use a
 gcc that knows of them?

 Probably I'm doing something wrong... it seems a case of deadlock!
