Depends what is 'echo': if it's a program or a shell command, you will
hit a limit.

Unfortunately, unlike with DJGPP, not every MinGW program accepts
response files.  ar and ld do, but that's about all there is, AFAIR.

(For the record: MinGW Make is limited to 32K characters on the
command line when invoking programs directly, and to 8K characters
when invoking via cmd.exe.)
