Should work again with cygwin-3.6.0-0.431.gad29c33229e5
This fixes the problem, thanks.
There are possibly still inconsistencies:
$ gcc -E -xc - <<<'#include <stdlib.h>' | grep arc4random_stir
void arc4random_stir(void);
$ gcc -E -xc - <<<'#include <bsd/stdlib.h>' | grep arc4random_stir
void arc4random_stir(void); // from cygwin/stdlib.h
void arc4random_stir(void); // from bsd/stdlib.h
$ gcc -E -xc - <<<'#include <stdlib.h>' | grep arc4random_addrandom
$ gcc -E -xc - <<<'#include <bsd/stdlib.h>' | grep arc4random_addrandom
void arc4random_addrandom(unsigned char *dat, int datlen);
$ gcc -E -xc - <<<'#include <bsd/stdlib.h>' | grep arc4random_buf
void arc4random_buf (void *, size_t); // from stdlib.h
void arc4random_buf(void *_buf, size_t n); // from bsd/stdlib.h
$ nm /usr/lib/libcygwin.a | grep ' arc4random'
0000000000000000 T arc4random
0000000000000000 T arc4random_addrandom
0000000000000000 T arc4random_buf
0000000000000000 T arc4random_stir
0000000000000000 T arc4random_uniform
$ nm /usr/lib/libbsd.dll.a | grep ' arc4random' || echo not found
not found
I guess:
- arc4random_addrandom() should be removed from libcygwin.a or added to
cygwin/stdlib.h.
- all arc4random*() should be hidden for __CYGWIN__ in bsd/stdlib.h.
