Subject: Move function nan_value to POSIX platform file
X-Git-Tag: upstream/4.7.83~22859
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2cfb4941a19cfa5749fe931fa296712947bd91e4;p=platform%2Fupstream%2Fv8.git

Move function nan_value to POSIX platform file

Strictly speaking NAN from math.h is not in a POSIX standard but in C99. However it seems that all our POSIX platforms have it.
