 * from: Onno van der Linden    c/o   [e-mail]
 *
 * Here's an idea how to automatically detect the version of NetBSD pcvt is
 * being compiled on:
 *
 * NetBSD 0.8 : NetBSD0_8 defined in <sys/param.h>
 * NetBSD 0.9 : NetBSD0_9 defined in <sys/param.h>
 * NetBSD 1.0 : NetBSD1_0 defined as 1 in <sys/param.h>
 * NetBSD 1.0A: NetBSD1_0 defined as 2 in <sys/param.h>
 *
 * The NetBSDx_y defines are mutual exclusive.
 *
 * This leads to something like this in pcvt_hdr.h (#elif is possible too):
 *
 *---------------------------------------------------------------------------*/

#ifdef NetBSD0_8
#define PCVT_NETBSD 8
#endif

#ifdef NetBSD0_9
#define PCVT_NETBSD 9
#endif

#ifdef NetBSD1_0
#if NetBSD1_0 > 1
#define PCVT_NETBSD 199
#else
#define PCVT_NETBSD 100
#endif
#endif

/*---------------------------------------------------------------------------
 * Note that each of the options below should rather be overriden by the
 * kernel config file instead of this .h file - this allows for different
 * definitions in different kernels compiled at the same machine
 *
 * The convention is as follows:
 *
 *	options "PCVT_FOO=1"  - enables the option
 * 	options "PCVT_FOO"    - is a synonym for the above
 *	options "PCVT_FOO=0"  - disables the option
 *
 * omitting an option defaults to what is shown below
 *
 * exceptions from this rule are i.e.:
 *
 *	options "PCVT_NSCREENS=x"
 *	options "PCVT_SCANSET=x"
 *	options "PCVT_UPDATEFAST=x"
 *	options "PCVT_UPDATESLOW=x"
 *	options "PCVT_SYSBEEPF=x"
 *
 * which are always numeric!
