|
|
* Here's an idea how to automatically detect the version of NetBSD pcvt is
|
|
* being compiled on:
|
|
*
|
|
* 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):
