--- Comment #1 from Federico Kircheis <federico.kircheis at gmail dot com> ---
I've missed a line while copy-pasting the test program, there was a missing ')'
at the end:
----
#define DIAGNOSTIC_HELPER0(x) #x
#define DIAGNOSTIC_HELPER1(kind, y) DIAGNOSTIC_HELPER0(GCC diagnostic kind #y)
#define DIAGNOSTIC(kind, warning, statements)\
_Pragma("GCC diagnostic push")\
_Pragma(DIAGNOSTIC_HELPER1(kind, warning))\
statements \
_Pragma("GCC diagnostic pop")
DIAGNOSTIC(error, -Wuninitialized,
int foo(int a, int b){return a;}
int main(){
int i;
return foo(i, i);
}
)
