Bug ID: 82919
Summary: Docs don't mention -Wimplicit-int is enabled in C99
mode
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: antox at ml dot lv
Target Milestone: ---
-Wimplicit-int is enabled by default in C99 mode (or later) just like
-Wimplicit-function-declaration. This is not documented (e.g.
https://gcc.gnu.org/onlinedocs/gcc-7.2.0/gcc/Warning-Options.html):
----
-Wimplicit-int (C and Objective-C only)
Warn when a declaration does not specify a type. This warning is enabled by
-Wall.
-Wimplicit-function-declaration (C and Objective-C only)
Give a warning whenever a function is used before being declared. In C99
mode (-std=c99 or -std=gnu99), this warning is enabled by default and it is
made into an error by -pedantic-errors. This warning is also enabled by -Wall.
-Wimplicit (C and Objective-C only)
Same as -Wimplicit-int and -Wimplicit-function-declaration. This warning
is enabled by -Wall.
