Subject: build-sys: Include <stdlib.h> in ./configure wchar_t test
X-Git-Tag: v2.35-rc1~318
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1632856ef19efb50c57c939b82a9ff712b3c0b09;p=thirdparty%2Futil-linux.git

build-sys: Include <stdlib.h> in ./configure wchar_t test

Without #include <stdlib.h>, this configure check fails for strict
C99/C11 compilers which do not support implicit function declarations
(which are a C90 feature removed from C99).
