-	This trivial patch causes gcc to emit a warning whenever
-	it generates a trampoline.  These are otherwise hard to
-	locate.  It is rigged to default ON - to have it default
-	to OFF remove the text 'Init(1)' from the common.opt
-	patch, leaving just 'Common Var(warn_trampolines)'.

-+ Warn about trampolines generated for pointers to nested functions.
-+ 
-+ A trampoline is a small piece of data or code that is created at run
-+ time on the stack when the address of a nested function is taken, and
-+ is used to call the nested function indirectly.  For some targets, it
-+ is made up of data only and thus requires no special treatment.  But,
-+ for most targets, it is made up of code and thus requires the stack
-+ to be made executable in order for the program to work properly.
