ecpg odd syntax error at array index

Hello,

seems odd, but why is the first SELECT a, quote: syntax error at or near "["
while the second one is OK ? Do spaces really make a difference for ecpg
before an array index ?

myfunction ()
{
EXEC SQL BEGIN DECLARE SECTION;
char chtm[23][19];
EXEC SQL END DECLARE SECTION;

EXEC SQL SELECT mycolumn INTO :chtm[ 0] FROM mytable WHERE ...;
EXEC SQL SELECT mycolumn INTO :chtm[1] FROM mytable WHERE ...;
}

Versions are:

ecpg (PostgreSQL 7.4) 3.0.0
Linux scaleo 2.4.18-4GB #1 Wed Mar 27 13:57:05 UTC 2002 i686 unknown
