Changes:
1999-09-21: Ivo Panacek <ivop@regionet.cz>
- added COMPILE_DL section
- more verbose php_info_ibase function
mostly stolen from pgsql.c for now
1999-10-05: Ivo Panacek <ivop@regionet.cz>
- safe rinit/rfinish: check for NULL so
rfinish could be called repeatedly
emalloc & co. replaced with malloc & co.
