`C-h f compile' details out how I can build over the compile command to
suit my needs.
For a higher order automation, here is an excerpt from `Info > ede >
Building and Debugging' (C-h i m ede RET m build TAB RET)
EDE provides the following “project-aware” compilation and debugging
‘C-c . c’
Compile the current target (‘ede-compile-target’).
‘C-c . C’
Compile the entire project (‘ede-compile-project’).
‘c-c . D’
Debug the current target (‘ede-debug-target’).
Build a distribution file for your project.
These commands are also available from the ‘Development’ menu.

Eitherways, it seems to be `configurable' into my project system.

Emacs does provide an interface to this shell command, with compile.
(Info > Emacs > Building > Compilation) details it out. Here is an
The default compilation command is ‘make -k’, which is usually
correct for programs compiled using the ‘make’ utility (the ‘-k’ flag
tells ‘make’ to continue compiling as much as possible after an error).
*Note Make: (make)Top. If you have done ‘M-x compile’ before, the
command that you specified is automatically stored in the variable
‘compile-command’; this is used as the default the next time you type
‘M-x compile’. A file can also specify a file-local value for
‘compile-command’ (*note File Variables::).

I do not understand the "Human Factors" ambiguity problem. So I refrain

You may try ply around with this:
(global-set-key (kbd "C-c C-c C-c")
(compile (format "gcc -c -o %s %s"
