note 15998 added to install.hpux

For PHP 4.0.6 under HP-UX 11.00, I ran into errors during the compilation related to "LC_CTYPE" and other "LC_" vars. The compilation complained that "LC_" such and such first used in such and such function. (I think the error first came up in php_pcre.c, then in basic_functions.c). The solution was to add "#include <locale.h>" to the php.h file. Compilation was successful after that was added, with no other issues. Used gcc 2.95.3, apache 1.3.20, bison 1.28, flex 2.5.4.a. -- http://www.php.net/manual/en/install.hpux.php http://master.php.net/manage/user-notes.php?action=edit+15998 http://master.php.net/manage/user-notes.php?action=delete+15998 http://master.php.net/manage/user-notes.php?action=reject+15998
