# Do whatever is necessary to enable as much C99 support as
# possible in the C compiler. Newer versions of compilers
# might default to supporting C99, but older versions may
# require a special flag.
#
# We do not want strict C99 support, as we may also want to
# use compiler extensions.
#
# Prior to CMake 3.1, setting CMAKE_C_STANDARD will not have
# any effect, so, unless and until we require CMake 3.1 or
# later, we have to do it ourselves on pre-3.1 CMake, so we
# just do it ourselves on all versions of CMake.
#
# Note: with CMake 3.1 through 3.5, the only compilers for
# which CMake handles CMAKE_C_STANDARD are GCC and Clang.
# 3.6 adds support only for Intel C; 3.9 adds support for
# PGI C, Sun C, and IBM XL C, and 3.10 adds support for
# Cray C and IAR C, but no version of CMake has support for
# HP C. Therefore, even if we use CMAKE_C_STANDARD with
# compilers for which CMake supports it, we may still have
# to do it ourselves on other compilers.
#
# In addition, CMake 3.5.2 seems to think that GCC versions
# less than 4.4 don't support -std=gnu99, which we need in
# order to get support for "for (int i = 0; i < n; i++) ;",
# which is another reason not to rely on CMake's CMAKE_C_STANDARD
# support.
#
# See the CMake documentation for the CMAKE_<LANG>_COMPILER_ID
# variables for a list of compiler IDs.
#
# We don't worry about MSVC; it doesn't have such a flag -
# either it doesn't support the C99 features we need at all,
# or it supports them regardless of the compiler flag.
#
# XXX - we add the flag for a given compiler to CMAKE_C_FLAGS,
# so we test whether it works and add it if we do. We don't
# test whether it's necessary in order to get the C99 features
# that we use; if we ever have a user who tries to compile with
