C.6 Using DDD with GNU Make
===========================

GNU Make support is rather new. As a programming language, GNU Make is
a bit of a stretch for DDD. There are no record structures or hash
tables, no pointers. Well, actually this does exist, but the records,
pointers and hash tables are fixed into the system.  There are Makefile
variables, "targets" (which sometimes refer to files), dependencies,
and commands. There is sort of an "scope" that for variables too.

   But much of the data display and visualization features of DDD are
disabled. However `info locals' does work and you can hover over a
variable and see its value.

   As with any scripting or interpreted language like Perl, stepping a
machine-language instructions (commands Stepi/Nexti) doesn't exist.

   Pay special attention when the prompt has extra angle
brackets--nested invocation of GNU MAKE. Quitting may merely exit out
of one of these nested invocations rather than leave the program.
