I'm using premake intensively and I think it'd be good if the "flags" function could be improved in the following way:
1) Add a linker option (if any) to make linktime warnings as errors when under FatalWarnings. E.g. for gcc, this involves adding the following to the command line: -Wl,--fatal-warnings
2) Add a new flag value called e.g. C99 that turns on compiler support for this version of the C standard. E.g. for gcc, this should add -std=c99 to the command line.
