Any way the new patch builds the iostream version of hello world. And it is going through the rest of the build: 1) Build 3 compilers with different long double formats; 2) Build non-bootstrap compilers with the compilers in step 1; 3) Build bootstrap compilers with the compilers in step 2; 4) Build spec for the 2 128-bit long double types. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meissner@linux.ibm.com, phone: +1 (978) 899-4797
