We are developing a quad precision floating point library for use with gfortran.
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.
Best regards,
Jerry
