ECPG: "EXEC SQL CREATE SCHEMA foo" Broken

Hi, please apply patch below to correct the EXEC SQL CREATE SCHEMA
construct in ECPG. Currently (versions 7.3.x, 7.4) the preprocessor
emmits "create scheme" in error, rather than "create schema".

A workaround also exists for those who require it (but I guess no-one
apart from me does since it's went unreported through 7.3), rather
than (checking omitted):

EXEC SQL CREATE SCHEMA foo;

you can use:

EXEC SQL BEGIN DECLARE SECTION;
char l_cmd[50];
EXEC SQL END DECLARE SECTION;

snprintf(l_cmd, sizeof(l_cmd), "CREATE SCHEMA foo");
EXEC SQL EXECUTE IMMEDIATE :l_cmd;

Thanks, L.
