OK, the reason of my asking was configure script in a 3rd party
application (namely apr-1.3.6) that generated strange warning about
sys/syslimits.h being good enoung for gcc but not for gcc -E.

it seems, they have a bug in checking for the presence of limits.h and
sys/syslimits.h and include them in a non-uniform manner later.

going to send them a patch
