>Description:
gcc HEAD added a new warning recently:

  warning: incompatible implicit declaration of built-in function 'malloc'

This happens with any standard library function.

This really spikes the test suite.  Most files in gdb.mi/*.c are affected.

My K&R 2nd edition, Appendex B, says:

  "A header must be included outside of any external declaration or definition and before any use of anything it declares."

So I think the compiler is right and gdb.mi/*.c are wrong.

>How-To-Repeat:
Run the test suite with gcc HEAD.
>Fix:
(1) Rewrite gdb_get_line_number so it works with MI.
(2) Update the copyright years in gdb.mi/*.exp.

(3) Enhance gdb.mi/*.exp to use gdb_get_line_number instead of absolute line numbers.
(4) Add copyright notices to gdb.mi/*.c.
(5) Add "#include" lines to gdb.mi/*.c.

I've already done (1) and (2).  (3) is in progress.
