When attempting to build the library under Cygwin, we are stopped because: __float128 is not supported when running the ./configure for the package. I suspect the issue may be related to newlib vs glibc, but I really don't know. Do any of the Cygwin maintainers have any hints about this? I am still investigating. It would be nice to have this quad precision capability under Cygwin. The library is a software floating point library and does not depend on having special hardware. We have it running on i686 and x86-64 Linux, but so far no luck under Windows. If I learn more in the next few days, I will report here. Any suggestions would be appreciated.
