  int SelectFunctionToJump(char *b, unsigned l)

  Is the external entry point, this routine calls to one routine that parses
the C source searching for functions, the methode is heuristic and doesn't
detect all the possible cases, in particular the K & R edition I style of
functions (totally obsolete).
  The routine creates a StringCollection with the functions found and then
creates a dialog box to select one. If the user select a function the
routine returns the line where the function starts if there are no functions
or the user choose cancel the routine returns -1.
  The parameters passed to the routine are:
  char *b: The buffer where the routines will search.
  unsigned l: The length of the buffer.

  Defining the label TEST you can test the module as an standalone program.

  Description:
  Puts the next word in Buffer. It skips white spaces, comments,
preprocesor lines, etc. So only words that can be interesting are collected.
If TakeOneCharToo!=0 the routine also collects single chars in Alone global
variable.

  Return:
  0 nothing found.
  1 a word.
  2 a single character
  3 a preprocessor line. The buffer contains the #xxx that started the line.
