 * Revision 1.5  2001/08/08 19:39:40  jelson
 * ARGH!  These are changes that made up tcpflow 0.20, which for some reason I
 * did not check into the repository until now.  (Which of couse means
 * I never tagged v0.20.... argh.)
 *
 * Changes include:
 *
 *   -- portable signal handlers now used to do proper termination
 *
 *   -- patch to allow tcpflow to read from tcpdump stored captures
 *
 * Revision 1.4  2000/12/08 07:32:39  jelson
 * Took out the (broken) support for fgetpos/fsetpos.  Now we always simply
 * use fseek and ftell.
 *
 * Revision 1.3  1999/04/21 01:40:14  jelson
 * DLT_NULL fixes, u_char fixes, additions to configure.in, man page update
 *
 * Revision 1.2  1999/04/13 23:17:56  jelson
 * More portability fixes.  All system header files now conditionally
 * included from sysdep.h.
 *
 * Integrated patch from Johnny Tevessen <j.tevessen@gmx.net> for Linux
 * systems still using libc5.
 *
 * Revision 1.1  1999/04/13 01:38:13  jelson
 * Added portability features with 'automake' and 'autoconf'.  Added AUTHORS,
 * NEWS, README, etc files (currently empty) to conform to GNU standards.
 *
 * Various portability fixes, including the FGETPOS/FSETPOS macros; detection
 * of header files using autoconf; restructuring of debugging code to not
 * need vsnprintf.
 *
 */

/*
 * Set up various machine-specific things based on the values determined
 * from configure and conf.h.
