Does anyone else think having __libc_read, __libc_write etc would be
handy?

Is something like this a "bad idea"[TM]?

It would be nice to be able to use something like
-D_LIB_ENTRY_LABEL=__libc_ or whatever, but I've not worked out how to
get that to work - I get either "__libc_ read" or "_LIB_ENTRY_LABELread"
