/* Program to extract function declarations from C/C++ source code
 *
 * Written by Eric R. Smith and placed in the public domain
 *
 * Thanks to:
 *
 * Jwahar R. Bammi, for catching several bugs and providing the Unix makefiles
 * Byron T. Jenings Jr. for cleaning up the space code, providing a Unix
 *   manual page, and some ANSI and C++ improvements.
 * Skip Gilbrech for code to skip parameter names in prototypes.
 * ... and many others for helpful comments and suggestions.
 *
 * Many extension were made for use in ARB build process
