It will work on Linux LE systems with glibc 2.32 (it may work with earlier glibcs). I've built parallel toolchains with all 3 long double formats. There are some tests in the test suite that fail if you configure 64-bit long doubles. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.ibm.com, phone: +1 (978) 899-4797
