Sephe,

thanks, that fixed it ;-)

This seems to happen when you do a buildworld with MACHINE == pc32 
followed by an installworld with MACHINE == i386. 
/usr/include/machine/param.h with the necessary definition doesn't seem 
to get installed then.

I'll commit a check to installworld similar to that done for buildworld 
to ensure that this can't happen.

A quick-and-dirty fix would be to edit makewhatis.c to define MACHINE 
temporarily (see patch). It can be removed then after a successful 
{build,install}world.

I assume you have failed to installworld before this compiling error.
If my assuming is correct then add following lines after last #include
... in src/usr.sbin/makewhatis/makewhatis.c:
#ifndef MACHINE
#define MACHINE "pc32"
#endif

Don't forget to nuke it once you have "a whole new world" :-)

BTW, before you installworld, please make sure to:
export MACHINE=pc32
Thank Sascha for this tip :-)

Hi,
