(hc2.1y is a script that runs "hc2 -B...")
The code does deserve some complaint, but the complaints made appear
to have nothing to do with the code itself. (I was using this test
file to see if my previous bug report was fixed with 2.1y, with or
without the `ansi' flag. Apparently not....)
It looks as though a line "#define ibm032 1" were being prepended to
the preprocessor *output*, and then fed to the next stage of parsing
without any further preprocessing.
Under 2.1s the results are the same as if "-Hansi" was not supplied
(i.e., still no complaint about the code, but otherwise okay).
The output with "-Hansi -Hnocpp" is only slightly better:
% hc2.1y -O -S xxx.c -v -Hansi -Hnocpp
