There are systems such as the Android NDK API level 24 has the
open_memstream() function but doesn't provide a prototype, adding noise
to the build:
builtin-timechart.c: In function 'cat_backtrace':
builtin-timechart.c:486:2: warning: implicit declaration of function 'open_memstream' [-Wimplicit-function-declaration]
FILE *f = open_memstream(&p, &p_len);
^
builtin-timechart.c:486:2: warning: nested extern declaration of 'open_memstream' [-Wnested-externs]
builtin-timechart.c:486:12: warning: initialization makes pointer from integer without a cast
FILE *f = open_memstream(&p, &p_len);
^
Define a LACKS_OPEN_MEMSTREAM_PROTOTYPE define so that code needing that
can get a prototype.
Checked in the bionic git repo to be available since level 23:
https://android.googlesource.com/platform/bionic/+/master/libc/include/stdio.h#241
FILE* open_memstream(char** __ptr, size_t* __size_ptr) __INTRODUCED_IN(23);
