2016-10-25 Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com>
* stdlib/bug-strtod.c: Refactor based on GEN_TEST_STRTOD_FOREACH.
* stdlib/bug-strtod2.c: Likewise.
* stdlib/tst-strtod-round-skeleton.c: Likewise.
* stdlib/tst-strtod6.c: Likewise.
* stdlib/tst-strtod.h (GEN_TEST_STRTOD_FOREACH): Use strfrom.
2016-10-25 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
* NEWS: Mention the addition of strfromd, strfromf, and strfroml.
