* config.h.in: Regenerated.
* configure: Regenerated.
* configure.ac: Add checks for getegid and __secure_getenv.
* io/unix.c (P_tmpdir): Fallback definition for macro.
(tempfile_open): New function.
(tempfile): Use secure_getenv, call tempfile_open to try each
directory in turn.
* libgfortran.h (DEFAULT_TMPDIR): Remove macro.
(secure_getenv): New macro/prototype.
* runtime/environ.c (secure_getenv): New function.

* io/unit.c (get_internal_unit): Default to ROUND_UNSPECIFIED.
(init_units): Likewise.
* io/write_float.def (determine_precision): New function.
(output_float): Take into account buffer with %f format, no need
for our own rounding if unspecified or processor specified
rounding.
(DTOA): Simplify format string, add parameters.
(FDTOA): New macros similar to DTOA, but using %f format.
(OUTPUT_FLOAT_FMT_G): Stack allocate newf, determine correct
precision and fill buffer.
(EN_PREC): New macro.
(determine_en_precision): New function.
(WRITE_FLOAT): For G format, move buffer filling into
output_float_FMT_G, use FDTOA for F format.
(write_float): Increase buffer due to F format.
