Bug #: 54162
Summary: Does not accept static global anonymous unions or
structs
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: j...@joshtriplett.org
C1X, and numerous other compilers, support static anonymous unions or structs
at file scope. For example, the following code should work with a C1X
compiler:
static union {
unsigned x;
unsigned y;
};
int main(void)
{
x = 5;
return y;
}
However, GCC says:
test.c:4:1: warning: unnamed struct/union that defines no instances [enabled by
default]
test.c: In function ‘main’:
test.c:8:5: error: ‘x’ undeclared (first use in this function)
test.c:8:5: note: each undeclared identifier is reported only once for each
function it appears in
test.c:9:12: error: ‘y’ undeclared (first use in this function)
