project I am working on (Recall - a distributed, fault-tolerant, replicated, storage framework @ http://www.fault-tolerant.org). Recall is written in C++. I need to include the postgres headers and there are some problems when including the headers w/C++. Attached is a patch generated from postgres/src that fixes my problems. I was hoping to get this into the main source. It's very small (2k) and 3 files are changed: backend/utils/fmgr/fmgr.c, backend/utils/Gen_fmgrtab.sh.in, and include/access/tupdesc.h. In C++, you get a multiply defined symbol because the variable (FmgrInfo *fmgr_pl_finfo) is defined in the header (the patch moves it to the .c file). The other problem in tupdesc.h is the use of typeid is a problem in c++ (I renamed it to oidtypeid). Thanks, Neal Norwitz
