Universal regarding targets but not regarding time as it's recent-ish:
2014-09-17 Jeff Johnston <jjohn...@redhat.com>
* libc/include/sys/features.h: Add __NEWLIB__ and
__NEWLIB_MINOR__ macros.
My autotester hasn't automatically updated to a version with this change as
there hasn't been a regression-free period for gcc since 2014-05-08-20:35:45
r210245. :(
More to the point, this test being the random only requirement for the last
newlib release seems spurious.
There's a _NEWLIB_VERSION and a __NEWLIB_H__ which would work for not just the
latest newlib version. Would it be ok to change to (suggesting) #ifdef
_NEWLIB_VERSION? Alternatively, we have an effective-target newlib which can
be used to define a NEWLINE_IN_CLASS_BLANK which can be used for other
misfortunate targets.
