Bug ID: 90690
Summary: Undocumented -Werror-implicit-function-declaration
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tim.ruehsen at gmx dot de
Target Milestone: ---
The command line option '-Werror-implicit-function-declaration' is listed by
`gcc -Q --help=warning[,C]` and also accepted by gcc 4.6 up to 9.1.
But `man gcc` doesn't mention this command line option. If this has been
obsoleted by `-Werror=implicit-function-declaration`, please do not list it
with '-Q --help=warning'. We use this to automatically enable *all* warnings
(something like clang's -Weverything).
Thank you !
