%  added MakeBuildFilename, and ERRSET, so Build more  robust
%  and more like  Compile-file. Also turned off break,
%  and do closing FASLEND in case of error.
% Edit by Cris Perdue, 23 Mar 1983 0856-PST
%  Added BuildFileFormat for Apollo as requested by Kessler
% 07-Mar-83  Nancy Kendzierski
%  Added load if-system, since many .build files use the if_system macro.
% 09-Feb-83  MLG
%  Changed Buildformat to use $pl/
