ESQL/C

This is a follow-up to my question from yesterday about migrating from esql/c programs from Informix 4.0 to 5.0. Basically, I have narrowed the problem down to the DECLARE statement in the .ec file. A program with the statement $DECLARE q_curs CURSOR FOR SELECT col1, col2, col3 FROM tablename INTO $colvar1, $colvar2, $colvar3 WHERE col1 = $var1 will not compile the DECLARE command, giving the error message: warning: improper pointer/integer combination: op "=" syntax error before or at: _FSO cannot recover from previous errors. undefined symbol: _FSO If the WHERE clause is commented out, the error does not go away. If the DECLARE part is eliminated, leaving only the SELECT (and commenting out the OPEN and FETCH associated with the DECLARE), the program compiles correctly. In examining the .c file created by cperf, I find the construct _FSO, which does *not* appear in my .ec file. I have tried including every header file esql/c may use (excluding the X/OPEN header), but this has not helped. I am at a complete loss now. Anyone have any ideas about what is going on?
