With -Werror several compiles fail because of:

"c:/winavr-20100110/lib/gcc/../../avr/include/util/delay.h:90:3: warning: #warning
"Compiler optimizations disabled; functions from <util/delay.h> won't work as
designed"

Which I know but don't care until I compile with optimization after everything is
working.  I couldn't find a compiler directive to treat "#warning" as a warning in
the presence of "-Werror".

I tried removing "-Wall" leaving:

"-fms-extensions -Werror=implicit-function-declaration" and tried
"-fms-extensions -Werror-implicit-function-declaration"

but the implicit declarations were still not treated as an error.
