<pre>Android's bionic (libc) basically has code like:
typedef long jmp_buf[10];
void sigsetjmp();
This triggers the warning:
<source>:2:6: warning: declaration of built-in function 'sigsetjmp' requires
the declaration of the 'jmp_buf' type, commonly provided in the header
<setjmp.h>. [-Wincomplete-setjmp-declaration]
void sigsetjmp();
^
The warning tells me to declare jmp_buf, which I believe I did w/ the typedef?
See also r367387.</pre>
