<pre>clang wrongly accepts:
extern int foo (void) __attribute__ ((const const));
Multiple attributes inside a single __attribute__ (()) should be required to be
separated by commas, so ((const, const)).
I tried gcc. It rejects the code:
gcc code0.c
code0.c:1:44: error: expected ')' before 'const'
extern int foo (void) __attribute__ ((const const));
^~~~~~
)
code0.c:1:51: error: expected ',' or ';' before ')' token
extern int foo (void) __attribute__ ((const const));
^</pre>
</div>
