Subject: [build] Default to short wchar_t in stddef.h
X-Git-Tag: v1.20.1~1524
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1aca99f3cf46fc8551895b30d974ade52a2ba489;p=thirdparty%2Fipxe.git

[build] Default to short wchar_t in stddef.h

sparse does not understand -fshort-wchar.  Default to using uint16_t
as a wchar_t if not explicitly specified by the compiler, to avoid
large numbers of spurious warnings from sparse.
