Patch to fix char signedness issue on ppc

Hello

On Linux/ppc, gcc uses unsigned char's by default. query.cpp constructs
an object of SQLParseElement and gives it a value of -1 for the "char"
parameter (n). Later this value is compared to -1, which will be 255
when using unsigned chars. The result is a wrongly thrown exception. The
attached patch changes the type to "short int" where the number is used.
