Acts as a caching pre-processor to C/C++ compilers, which often results in a 5 to 10 times speedup in common compilations. [Open Source, GPL] http://ccache.samba.org/
Caches compiled object files to dramaticly speed up compiles. More convenient than make, and speeds up builds (like RPM builds) that make doesn't. Obsoleted by ccache. http://www.erikyyy.de/compilercache/
Creates fully cross linked documentation systems and manuals in PDF, HTML, HTML Help, Windows Help and RTF from C/C++ or Delphi/Pascal source code. http://www.doc-o-matic.com/
Designed to smoothly integrate the tasks of working with source files, compiling, and debugging, in short everything involved in developing code. (New Planet Software) http://www.newplanetsoftware.com/jcc/
Suite++ includes both positive and negative tests for comparing compiler behavior to the ANSI/ISO C++ Standard. LibSuite++ tests the conformance of the C++ library. (Plum Hall, Inc.) http://www.plumhall.com/suites.html
A code generator that integrates equations based at human readable form in an XML file, it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in selected hardware architecture. [Open source, http://www.xmds.org/
