Thank you Michael,
that fixes that problem. My build now gets further, but I get an error and a
seg-fault later in the build.

I have a file that contains the following line :


EXEC SQL FETCH ABSOLUTE :count SEARCHCURSOR INTO
    :db.contact_id, :db.uname, :db.type, :db.parent,
    :db.name, :db.phone, :db.fax, :db.email, :db.description,
    :db.custom_data, :db.value, :db.relevance,
    :db.parentName :vl_parentName,
    :db.keywords :vl_keywords,
    :membOfRecordCount;

this has worked in every version of ECPG since 7.4 (when we started using
Postgres). I now get the following error :

$ /usr/local/pgsql/bin/ecpg -t -o contactRecord.cxx -I
/usr/local/pgsql/pgsql/include contactRecord.pgC

Starting program: /usr/local/pgsql.8.3.rc1.patch/bin/ecpg -t -o

-------------
Running under GDB gives a stack trace as :

-----------------------
Apart from the seg-fault, is there any particular reason I can't use a variable
in the FETCH anymore? It's always worked in the past and would seem to be an
important capability.
