make is a tool to automate the recompilation of your programs. Rules for rebuilding your program are contained in a makefile. When given the right rules, make will only recompile those files that have changed since the last compile.
There are at least two versions of make available on our systems: the vendor supplied make, and GNUmake. /s/std/bin/make is GNU make. Each vendor's make may be a little bit different, but most makefiles should work with any make, unless you use special features.

makedepend is a tool to process C and C++ source files and determine which include files each one depends upon. Makedepend can automatically generate the dependency list in your makefiles for use with the make program.
Makedepend reads each sourcefile in sequence and parses it like a C-preprocessor, processing all #include, #define, #undef, #ifdef, #ifndef, #endif, #if and #else directives so that it can correctly tell which #include, directives would be used in a compilation. Any #include, directives can reference files having other #include directives, and pars- ing will occur in these files as well.
The manual page has a good example of how makedepend is used.

Editor tags allow the you to jump directly to the declaration of a function, #define, or typedef, while in a text editor.
You need to rebuild the tags file whenever you add or move declarations in your source files.
Ctags and etags work for C and C++, Fortran, Scheme, Lisp, pascal, lex, and yacc source files.
C++ variable names are encoded ("mangled") to include information about type overloading. In order to debug or namelist a C++ object file, it may be necessary to demangle the names first. c++filt is a filter program to demangle C++ names.
It is often very useful to pipe the standard output from the linker to c++filt. This will demangle the names of missing symbols, making it easier for you to tell what is missing.
cdecl and c++decl are tools to help you compose, or decypher C and C++ type declerations.
You can enter an english description of the type you wish to declare, and cdecl will print an appropriate declaration for you. Or, you can type in a declaration that you do not understand, and cdecl will explain it in english.
cxref reads the named C source files and produces on the standard output a cross reference of all the identifiers and constants in the files.
protoize is a tool to add ANSI C function prototypes to non-ANSI C programs. This is useful if you are converting existing code to ANSI C.
unprotoize is a tool to remove function prototypes from ANSI C programs.
