Both Linux and OpenBSD have LOGIN_NAME_MAX available when including limits.h, FreeBSD, Darwin and possibly others don't. FreeBSD (and maybe Darwin) have MAXLOGNAME, so try to use that if available. Otherwise use _POSIX_LOGIN_NAME_MAX, but only has a fallback since it has a lower value (9 at the time of writing). If everything fails, use 32 which is what OpenBSD use by default; OpenSMTPd also defaults to it. (compat copied from kamid.)

steal more (good) stuff from mandoc-portable :)

was a mistake on my part and a leftover from the first iterations. Initially I only stole a few bits, that's why the comment but not the copyright, but then i threwed out and restarted using oconfigure. Then the configure script has its own independent changes, but need to give attribution nevertheless.

gmid 1.8.3 "Lightbulb Sun" bugfix release ========================================= Released March 27, 2022. signify(1) pubkeys for this release: RWTy3UJQzpxBUAymBwb2EGLLm0b3H/1n8hzhaC9HYFYzNuTavGt9QSwC Bug Fixes ~~~~~~~~~ * fix a possible out-of-bound access in the CGI handling. It was introduced last October during a refactoring, but due to how many malloc(3) implementations works this hasn't been found until now. Otto' malloc is more strict fortunately.

gmid 1.8.2 "Lightbulb Sun" bugfix release ========================================= Released March 26, 2022. signify(1) pubkeys for this release: RWTy3UJQzpxBUAymBwb2EGLLm0b3H/1n8hzhaC9HYFYzNuTavGt9QSwC Bug Fixes ~~~~~~~~~ * fix a CGI timing issue: if a connection handled by a CGI scripts is interrupted with the right timing it causes the server process to exit with "fatal in client_by_id: invalid id X". New Features ~~~~~~~~~~~~ * add a new block `type { ... }' to define mime types mapping. Improvements ~~~~~~~~~~~~ * use shell built-in `command' instead of which(1), prodded by cage and Allen Sobot. * configure script: allow to set MANDIR from cmdline (Allen Sobot) * add systemd-sysusers sample file in contrib/ (Nakaya) * [linux/seccomp] allow fstatat64(2), llseek(2) and sigreturn(2), needed by glibc on armv7. (Tobias Berger) * [linux/seccomp] tightens rules by allowing openat(2) only with the O_RDONLY flag.

should have been done already in 12fcba2; reminded by Allen Sobot, thanks!
