Here's the > output of make -k (after Configure) Sigh. I should've known the tiny test program I used that beautifully displayed the shortening problem didn't represent the real world. Even -Wconversion (without escalating the warning to an error) includes a huge pile of different, unrelated potential problems when thrown at the Perl sources. The closest we could come might be: -Accflags='-Wconversion -Wno-sign-conversion -Wno-shorten-64-to-32' which is kind of a mouthful and still generates so many warnings with existing code that it would be hard to see any new ones, even if people could develop the habit of reviewing and acting on warnings, which experience shows usually won't happen. So I agree with you, but I don't know what else to recommend. Side note: -Wshorten-64-to-32 might be useful when chasing the I32 bug on a platform with -Duse64bitint enabled.Thread Previous | Thread Next
