Hi, Is it possible to build perl 5.30.0 such that "perl -V" output does NOT specify "USE_PERL_ATOF" ? If not, then the obvious question is "Why do we bother specifying it ?" Additionally, I would find it very helpful if there was something in the "perl -V" output that would tell us whether perl was assigning floating point values using strtod/strtold (whichever is appropriate for perl's nvtype) or not. This could probably best be achieved by having "perl -V" indicate the status of both $Config{d_strtod} and $Config{d_strtold}. For quadmath builds, there's currently no confusion as they always assign floating point values using strtoflt128. Yet their "perl -V" output still lists "USE_PERL_ATOF", which I find rather puzzling. Cheers, RobThread Next
