Getting "function declaration isn't a prototype [-Werror=strict-prototypes]" when compiling an application in C style using gcc compile

[vnkbabu]

Hi, One of our customer is trying to compile the ODBC application using gcc compiler in C style, they are encountering the following errors, due to pre-Ansi declarations of empty parameter list functions and using -Werror=strict-prototypes option for compiling.

Could you please fix this issue as customer who is using the strict-prototypes are getting impacted.
