Description Florian Weimer 2023-01-12 07:14:22 UTC 
This package calls strcasestr without a previous declaration. The implicitly declared return type is int, which means that the function can return 0 even if the string is found, if we are unlucky. Further compiler versions will also reject such implicitl function declarations, leading to build failures.

Filing this here for tracking purposes because upstream does not seem to have a mailing list/bug tracker.
