After much head banging and web surfing, I finally fixed the plpgsql.dll
build problem. I was pointed in the right direction by Joost Kraaijeveld.
The solution was to change Gen_fmgrtab.sh.in, which generates fmgr.h,
as follows:
diff Gen_fmgrtab.sh.in.orig Gen_fmgrtab.sh.in
139c139,144
< extern FmgrInfo *fmgr_pl_finfo;

fmgr_pl_finfo is data and not a function, so I guess that it needs to be
explicitly imported/exported via __declspec(dllimport)/__declspec(dllexport),
respectively.
Does anyone know whether or not older Cygwin versions of binutils
automatically exported data items?
Thanks,
Jason
