Checking silc tookit for bad string functions using:

egrep -r '[^_.>a-zA-Z0-9](str(n?cpy|n?cat|xfrm|n?dup|str|pbrk|tok|_)|stpn?cpy|a?sn?printf|byte_)' .

Result is below.  Not great but about 300 is a manageable target to audit and improve.

./contrib/regexpr.c:	      strcpy(buf, "end");
./contrib/regexpr.c:	      strcpy(buf, "bol");
./contrib/regexpr.c:	      strcpy(buf, "eol");
./contrib/regexpr.c:	      strcpy(buf, "set ");
