Bug #: 54817
Summary: Warning about extern declarations in C and C++ files.
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org

Hi!
I think will be good idea if GCC will produce warnings when extern declarations
are placed in C/C++ files (not included from other files).
Such declarations are definitely belong to headers, so their appearance in
source files are indication of bad coding practices.
Intel compiler produces such warnings as "warning #1419: external declaration
in primary source file".
Eugene.
