# SYNOPSIS
#
# WOLFSSL_DARWIN_USING_CLANG
#
# DESCRIPTION
#
# With the advent of Apple Xcode v5.0, the old tool sets are missing from
# the distribution. The provided "gcc" executable wrapper accepts the
# "-pthread" flag, and passes it to the underlying "clang" which chokes
# on it. This script checks the version of the gcc executable to see if
# it reports it is really "clang".
#
# The value is placed in the wolfssl_darwin_clang variable.
