I believe some projects (binutils and gcc maybe?) draw a distinction

    GDB requires an ISO C (ANSI C) compiler.  If you do not have an ISO
 C compiler for your system, you may be able to download and install
 the GNU CC compiler.  It is available via anonymous FTP from the

    GDB uses Expat, an XML parsing library, to implement some target-specific
 features.  Expat will be linked in if it is available at build time, or
