# VxWorks system environments have been GCC based for a long time and we need
# to make sure that our files and the system ones use distinct macro names to
# protect against recursive inclusions. We achieve this by temporarily
# substituting the headers used by stmp-int-headers with alternative versions
# where we add some version indication in the inclusion-protection macro
# names.
# Before the standard stmp-int-headers operations take place, arrange to
# copy the current version of the relevant header files locally, generate
# the alternate version and replace the original version with ours:

sed -e "s/_LIMITS_H__/_LIMITS_H__$${ID}_/" < $(srcdir)/$*.h > $@

# Then arrange to restore the original versions after the standard
# operations have taken place:
