--- Comment #26 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-11-25 17:15:31 UTC --- All the various options equivalent to -std=c99 now map to -std=c99 using Alias in the .opt file, so specs only need to handle that one spelling. The same applies with -std=gnu99. Note that -ansi and -std=c90 are not marked as Aliases for each other because the meaning of -ansi depends on whether C or C++ is being built.
