Subject: [PATCH] All FreeBSD do not implement the function sysconf with
 arguments _SC_GETGR_R_SIZE_MAX , _SC_TTY_NAME_MAX:_SC_GETPW_R_SIZE_MAX.

php use this sysconf() in:

main/main.c php_get_current_user()
main/fopen_wrappers.c php_fopen_primary_script()
ext/posix/posix.c posix_getpwnam(), posix_getpwuid(), posix_getgrnam(),
posix_getgrgid()
ext/standard/filestat.c php_get_uid_by_name(), php_get_gid_by_name()
