* io/write.c (write_d, write_e, write_f, write_en,
write_es): Add precision compemsation parameter to call.
(set_fnode_default): Adjust default widths to assure
round trip on write and read. (write_real): Adjust call to write_float.
(write_real_g0): Calculate compensation for extra precision and adjust
call to write_float.
* io/write_float.def (output_float_FMT_G_): Use volatile rather than
asm volatile to avoid optimization issue. Correctly calculate the
number of blanks (nb) to be appended and simplify calculation logic.
(write_float): Increase MIN_FIELD_WIDTH by one to accomodate the new
default widths. Eliminate the code that attempted to reduce the
the precision used in later sprintf functions. Add call parameter to
compensate for extra precision.
