That does resolve the issue for me on 2.6. I'm not sure what, precisely,
changed or when, but:
On macOS 10.11.6/Xcode 7.3.1 I do not have this issue with 2.5.
On macOS 10.12.6/Xcode 9 it doesn't work out of the box with at least 2.5 or
2.6.
Both environments have fparseln as part of libc.
FPARSELN(3) BSD Library Functions Manual FPARSELN(3)

int flags);
