--- Comment #38 from Thomas Henlich <thenlich at users dot sourceforge.net> 2011-04-20 12:38:53 UTC --- As an alternative we might consider leaving the code as it was before and instead putting OUTPUT_FLOAT_FMT_G(4) OUTPUT_FLOAT_FMT_G(8) OUTPUT_FLOAT_FMT_G(10) into separate files and compile with -mpc32 -mpc64 -mpc80 respectively.
