All of the below changes are backports from 4.3+dbg-1.5

New and Changed Features

• --search parent -- I really like this one.
• --tasks -- the definition of a "tasks" has been simplified. Now, it is simply a target that has a description comment (#:) before it. After many years of using this myself, I highly encourage people to start using description comments more. Output from running remake --tasks is nicer because we use spaces to align columns rather than tabs.

Debugger Changes

• Commands with file expansion now use glob(), not word_expand() (Thomas did this too). Previously source used to POSIX.1-2008 wordexp(), but this is not available on BSD-ish systems. glob() is more general, and GNU make ships with its own glob() function when none is provided in the underlying OS library.
• load command added eval command removed. eval never worked and it attempted to be the same thing as load; load is the gdb name.
• $(debugger) function fixed. This function gave an virtual memory exhausted on exit. This has been fixed. The required parameter for this function, a tag name, is now shown on entry
• info tasks has been added. It is basically the same thing as remake --tasks
• Description lines are now shown on in info targets and list commands
• The debugger now disallows any inside post-mortem debugging
