The flags were added in [ffd9c6e4be106d3922c69d9c81afaa12111767fa/macports-ports]

[mascguy (Christopher Nielsen)]

Ah yes, we should only add those flags when the compiler is Clang. Will fix tomorrow, thanks for the heads-up!

Great, thanks!

Apple's GCC 4.2 does not know warnings à la -W-no-<whatever. Another question is why we end-users need to use compiler switches that only might tell something the developer…

[Christopher Nielsen <mascguy@…>]

In b2960de97ef2c6cb4c43d5026d02193e7ddc42e7/macports-ports (master):

gtk2{,-devel}: limit new compiler flags to clang

Fixes: #69829

[ballapete (Peter "Pete" Dyballa)]

It built now.

Great, thanks for confirming Pete!
