Another victim of -Werror=implicit-function-declaration being set by default:

This is the well-known implicit declaration of function issue with Xcode 12 and later that needs to be fixed in the usual way (include the right headers in the right places).

[ryandesign (Ryan Carsten Schmidt)]

Almost done fixing this and modernizing the rest of the port, except that #62292 is causing trouble.

Replying to ryandesign:

#62292 is closed now

[ryandesign (Ryan Carsten Schmidt)]

In db23a98e5ab6fed765dda5bc9bd7b646a619ccc6/macports-ports (master):

anacron: Fix implicit declaration of functions

Closes: #62247

Also modernize checksums, rename patchfiles, and reorganize portfile
slightly.

works for me.

thanks!
