Thank you for the explanation. I tried to read the wiki page. Unfortunately, it 
is above my pay grade. I'll have to leave it to someone else to file a ticket.

We have a wiki page with an in-depth explanation of what this warning 
means: 


The executive summary for end users is that this is something that the 
port's maintainer needs to look into, so you can file a ticket about it, 
but it may or may not indicate a significant problem.

It means that a function was not declared as returning a type, and so it's 
assumed to return "int"; I regard this as sloppy programming, and is to be 
avoided by serious programmers i.e. those concerned about security etc.

Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration; check that features were not accidentally disabled:

[Michael Newman via macports-users]

When upgrading MacPorts this morning I noticed the following message wizzing by:

Warning: Configuration logfiles contain indications of 
-Wimplicit-function-declaration; check that features were not accidentally 
disabled:

This right after:

--->  Configuring xorg-libxcb

I've never seen "Wimplicit" used before and wondered what it meant. When I 
searched I got:

Your search - -Wimplicit - did not match any documents.

Can someone please explain what this warning is about and just what "Wimplicit" 
means?

Each occurrence must be investigated and handled individually. File bug reports.

Warning: Configuration logfiles contain indications of -Wimplicit-function-declaration

[Michael Newman via macports-users]

Today I finally installed Big Sur and followed the MacPorts migration guide. I 
don't see any errors; no failures to build. However, I did get seven of these 
warnings:

Warning: Configuration logfiles contain indications of 
-Wimplicit-function-declaration; check that features were not accidentally 
disabled:

It was found in the following logs:

lynx2.8.9rel.1/config.log
clamav-0.103.2/config.log
anholt-libepoxy-d51a358/config.log
ghostpdl-9.54.0/config.log
graphviz-2.40.1/config.log
gst-libav-1.16.2/config.log
gst-plugins-bad-1.16.2/config.log

I have no idea what a "Wimplicit-function-declaration" is. I tried to search 
around, but was unable to enlighten myself. I gather it has something to do 
with C; about which I know nothing. If this warning is explained somewhere, 
please provide me with a link.

Do I need to do something about these, or are they ignorable?
