for installed header files, add comment saying where they came from 15 years ago			`/* this header file comes from libowfat, http://www.fefe.de/libowfat/ */`
buffer stuff from Olaf and ip[46]_fmt stuff from me. 24 years ago			`#ifndef IP4_H`
			`#define IP4_H`

make headers work in C++ add two more variable length integer encoding functions 13 years ago			`#ifdef __cplusplus`
			`extern "C" {`
			`#endif`

now that gcc 11's static analyzer looks at array bounds in arguments like "char ip[4]", let's be more strict about that 4 years ago			`size_t scan_ip4(const char *src,char ip[4]);`
			`size_t fmt_ip4(char *dest,const char ip[4]);`
renamed ip[46]_fmt to fmt_ip[46] 24 years ago

add prototype for dns_name6 (Rolf Eike Beer) add FMT_IP4 and FMT_IP6 for consistency 20 years ago			`#define FMT_IP4 20`
