Description

It emits several warnings about types mismatch

In below compile warnings most important are [-Wlto-type-mismatch] however it would be good to clean the code to calm down all other warnings as well

There are reasons why we sometimes don't consult the return code. That is even declared in the code with a cast to void. Further we use gpg_error_t and int interchangeable under the assumption that an unsigned int and an int value have the same bit pattern.

In this case it is not about don't consult the return code or casting sometning byt messy declaration in header files and .c files.
Please have look closer one more time on [-Wlto-type-mismatch] warnings.
