1250 *** When I try to use the PostgreSQL functions, I get a message about
1251 undefined symbols.
1252
1253 The only known case in which this happens is if you are using gcc, you
1254 configured with --error-checking=all and --with-modules, and you
1255 compiled with no optimization. If you encounter this problem in any
1256 other situation, please inform xemacs-beta@xemacs.org.
1257
1258 This problem stems from a gcc bug. With no optimization, functions
1259 declared `extern inline' sometimes are not completely compiled away. An
1260 undefined symbol with the function's name is put into the resulting
1261 object file. In this case, when the postgresql module is loaded, the
1262 linker is unable to resolve that symbol, so the module load fails. The
1263 workaround is to recompile the module with optimization turned on. Any
1264 optimization level, including -Os, appears to work.
