Re: makeinfo removes info file without necessity

[Karl Berry]

    For comparison, when gcc compiles a file, "gcc -c foobar.c", it does not
    remove foobar.o when there are syntax errors in foobar.c or one of its
    included files.

I agree with you that it would be better to not remove the output file.
It happens now because the output file(s) from the current run 
are built directly into their final location, so the old files are wiped
out at the beginning of the run.

Anyway, I'll work on fixing this at some point.  Thanks for the report.
