Subject: stdlib/tst-strtod-round.c: Fix build on ARM

|
|
|
||
|
|
Building this test on ARM fails because the prototypes for the long
|
||
|
|
double variants of the math functions are unavailable.
|
||
|
|
|
||
|
|
Add an additional include guard to math.h that enables long double math
|
||
|
|
function declarations if _LIBC_TEST is defined and define _LIBC_TEST in
|
||
|
|
stdlib/tst-strtod-round.c.
|
||

* math/math.h: Define long double math functions if
|
||
|
|
_LIBC_TEST is defined.
|
||
|
|
* stdlib/tst-strtod-round.c: Define _LIBC_TEST.
