[PATCH/committed] libgloss: bfin: fix various warnings

[Mike Frysinger]

No functional changes here, just fix warnings the compiler noticed.

bfin/syscalls.c:156:13: warning: conflicting types for built-in function ‘memset’

bfin/syscalls.c: In function ‘_unlink’:
bfin/syscalls.c:193:3: warning: passing argument 2 of ‘do_syscall’ discards qualifiers from pointer target type
bfin/syscalls.c:33:1: note: expected ‘void *’ but argument is of type ‘const char *’

bfin/syscalls.c: In function ‘_exit’:
bfin/syscalls.c:104:1: warning: ‘noreturn’ function does return
