I've been playing with a board file that forces every testcase to
include a header file that does something like:
#define main __gdb_testcase_main
and then links an actual main() function that does some
initialization and then jumps to __gdb_testcase_main.
That runs into a number of testcases relying on main not having an
explicit return statement, like e.g.,:
gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/catch-follow-exec.c:27:1: warning: non-void function does not return a value [-Wreturn-type]
gdb/build/gdb/testsuite/../../../src/gdb/testsuite/gdb.base/catch-signal.c:47:1: warning: non-void function does not return a value [-Wreturn-type]
We don't get those warnings without my board because it is valid to
not explicitly return from main. There's an implicit "return 0;".
Since it doesn't hurt to be explicit, I've went ahead and added the
explicit return statements.
Also, a couple testcases either don't explicitly specify main's return
type, or return void. Those are tweaked to explicitly return int.

* gdb.texinfo (Implementing a Remote Stub): Explain that you
should transfer control to the stub in the startup code instead of
in main. Mention the need to get past the initial breakpoint.
