add missing return types to main()

A similar treatment (adding explicit void to main) should be given to the following files:

trylsock.c
tryrsolv.c
trysyslog.c

[DerDakon]

good catch, no idea why I did not spot them.

The point is: main() is void everywhere, because it does not return and the return code comes from _exit(). I avoid _exit() here to not drag in more headers for no reasons, and just make it int main() and return 0;.

Nowhere in the codebase does it return from main. Everywhere it calls _exit. We should preserve that behavior.

Btw, Clang now issues these warnings:

qmail-qmqpc.c:138:1: warning: return type of 'main' is not 'int'

[DerDakon]

I'm back to "int main()" now. Fixing one warning with another does not help, and the consistency doesn't give us anything, especially as it's only about try*.c where noone needs to look on any bigger API or structure.
