ECPG: Make the preprocessor emit ';' if the variable type for a list of

variables is varchar. This fixes this test case:int main(void){ exec sql begin declare section; varchar a[50], b[50]; exec sql end declare section; return 0;}Since varchars are internally turned into custom structs andthe type name is emitted for these variable declarations,the preprocessed code previously had:struct varchar_1 { ... } a _,_ struct varchar_2 { ... } b ;The comma in the generated C file was a syntax error.There are no regression test changes since it's not exercised.Patch by Boszormenyi Zoltan <zb@cybertec.at>
