No, because all of __builtin_isinf, __builtin_isinff, __builtin_isinfl may
fall back to library functions isinf, isinff, isinfl and Solaris libc/libm
doesn't have those functions.

No, because again all the __builtin_finite* functions may fall back to
library functions and the only one of those Solaris has is plain "finite".
