52 * Here's an idea how to automatically detect the version of NetBSD pcvt is
55 * NetBSD 0.8 : NetBSD0_8 defined in <sys/param.h>
56 * NetBSD 0.9 : NetBSD0_9 defined in <sys/param.h>
57 * NetBSD 1.0 : NetBSD1_0 defined as 1 in <sys/param.h>
58 * NetBSD 1.0A: NetBSD1_0 defined as 2 in <sys/param.h>
60 * The NetBSDx_y defines are mutual exclusive.
62 * This leads to something like this in pcvt_hdr.h (#elif is possible too):
64 *---------------------------------------------------------------------------*/
76 #define PCVT_NETBSD 199
78 #define PCVT_NETBSD 100
82 /*---------------------------------------------------------------------------
83 * Note that each of the options below should rather be overriden by the
84 * kernel config file instead of this .h file - this allows for different
85 * definitions in different kernels compiled at the same machine
87 * The convention is as follows:
89 * options "PCVT_FOO=1" - enables the option
90 * options "PCVT_FOO" - is a synonym for the above
91 * options "PCVT_FOO=0" - disables the option
93 * omitting an option defaults to what is shown below
95 * exceptions from this rule are i.e.:
97 * options "PCVT_NSCREENS=x"
98 * options "PCVT_SCANSET=x"
99 * options "PCVT_UPDATEFAST=x"
100 * options "PCVT_UPDATESLOW=x"
101 * options "PCVT_SYSBEEPF=x"
103 * which are always numeric!
