    g++ not recognizing functions

    I'm trying to compile source code for an application i downloaded
    (gdb 5.3).
    I am using the g++ 3.2.1 compiler.
    For some reason, it stumbles on function declarations that
    look like this:

    set_cplus_marker_for_demangling (ch)
    int ch;

    It says:
    cplus-dem.c:93: `ch' was not declared in this scope
    cplus-dem.c:94: variable or field `set_cplus_marker_for_demangling' declared
    cplus-dem.c:94: `int set_cplus_marker_for_demangling' redeclared as different
    kind of symbol
    ../include/demangle.h:120: previous declaration of `void

    I.e. it expects the declaration to be
    "void set_cplus_marker_for_demangling (int ch)".

    How do I force it to recognize that kind of declaration? Obviously
    the authors of gdb were able to compile their code somehow, so
    I'm guessing that I'm missing some comiler option. Does anyone have any idea?
    Thanks in advance.

    You have old style C code

    The function declaration is old style Kernighan and Ritchie and probably is no longer supported by your compiler's default configuration. I expect there is a switch you can set, check your man pages and look up "Kernighan and Ritchie" or "K&R"

    It is not that old programmers are any smarter or code better, it is just that they have made the same stupid mistake so many times that it is second nature to fix it.
