This is all tiny stuff - allow overriding WIDENED_PROTOTYPES from the hints
file, missing NO_SIGNAL conditionals, remove a GCC-ism, conditional indentation,
void return in a non-void function.
PORTS: Please make sure I've done the right thing for/to your code.
This patch adds a new winproc that lets the window port approve or cancel
the suspend request - this should take care of the Mac Qt lockup issue.
In addition, Unix suspend is restricted to accounts that can use the shell
if SYSCF is defined.
More warning bits that never got committed.
More appropriate compiler flags for warning checks (macosx only for the moment).
The changes in dgn*[lc] just rename line_number to nh_line_number to avoid a
clash, so no need to regenerate the lex output.
