Bug#591529: <sys/systm.h> does not compile

[Tuco <tuco.xyz@gmail.com>]

Package: kfreebsd-kernel-headers
Version: 0.47
Severity: normal

When trying to build getnetconfig.c (obtained from src/sys/rpc/ in FreeBSD):

In file included from getnetconfig.c:35:
/usr/include/sys/systm.h:46:62: error: sys/stdint.h: No such file or directory
In file included from getnetconfig.c:35:
/usr/include/sys/systm.h:137: warning: no previous prototype for ‘longjmp’
/usr/include/sys/systm.h: In function ‘longjmp’:
/usr/include/sys/systm.h:137: error: expected declaration specifiers
before ‘__dead2’
/usr/include/sys/systm.h:138: error: expected ‘)’ before ‘addr’

lots of errors follow, this header is unusable :-(
