Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration; check that features were not accidentally disabled:
  exit: found in gsl-2.7.1/config.log
  strchr: found in gsl-2.7.1/config.log

To fix the implicit declaration of exit, please apply the patch attached to this bug report:

​https://savannah.gnu.org/bugs/index.php?63679

The implicit declaration of strchr is intentional and should be suppressed according to WimplicitFunctionDeclaration#strchr by adding:

# https://trac.macports.org/wiki/WimplicitFunctionDeclaration#strchr
configure.checks.implicit_function_declaration.whitelist-append strchr

[Dave-Allured (Dave Allured)]

Patch is now applied upstream. GSL version 2.8 release including this fix is imminent.

[Dave-Allured (Dave Allured)]

Oh sorry, I forgot about the second part above, whitelist strchr. That is still needed in the portfile.
