各位好：

    我在centos8.4  arm架构下编译IvorySQL 3.3源码时，如果同时编译doc会提示错误。

下面是我的编译选项：
$ ./configure '--prefix=/opt/isql16' '--with-openssl' '--with-includes=/usr/include/openssl' '--with-icu' '--with-lz4' '--with-zstd' '--with-libxml' '--with-llvm'

$ make world
...
...

 &biblio;
         ^
postgres.sgml:301: parser error : Entity 'biblio' not defined
 &biblio;
         ^
