From: Dan McGregor <dan.mcgre...@usask.ca>
The lxdialog.sh script compiles a short program as a link test. That
test program relied on an implicit return type of the main function,
but gcc >= 14 now warns on that by default. This caused the test
to fail and prevented menuconfig from starting.
Use a full function declaration to fix this, allowing menuconfig to
once again run on a newer host.

+Subject: [PATCH] menuconfig,check-lxdiaglog.sh: Fix gcc warning
+
+New gcc warns by default if a function is declared without a return
+type. Use a full c99 function declaration for main in the test.
