sys/stat.h with Motif on HP-UX B10.20

Hi,

I'm trying to compile code that includes both sys/stat and Motif
libraries, but the presence of the Motif includes (regardless of
position) seems to prevent the stat.h from being included. In fact,
running the application through the preprocessor results in only
something like:
# 1 "stat.h"
# 14
when a Motif include is present, otherwise the whole file gets
included. I suppose I could cut-and-paste preprocessor output and
compile that, or split the source files into stat.h-only and
Motif-only, but is there a reason for this, or a better workaround?

Thanks
