Inform 6.36

I know that there was some discussion not so very long ago about the best options to use when compiling, but I can’t seem to find it now. The basic compilation command of

cc *.c -o inform

works fine, but weren’t some switches for optimization recommended?

If there were, these switches do not seem to be mentioned in either the current release notes or the readme.txt file included with source. Would it be possible to add the correct invocation to one or both documents?
