Hi,
i've noticed in two cases of gmp and mpfr that if LTO is used when
configure is executed then it produces wrong checks.
For example in gmp
checking format of `double' floating point... unknown
BUILDSTDERR: configure: WARNING: Could not determine float format.
BUILDSTDERR: configure: WARNING: Conversions to and from "double" may be slow.
I had to do this to fix it:
I wonder how many packages are wrong configured. Is there any way to
fix this better way? Maybe pushing -flto on %make_build ?
