# Try to enable as many C99 features as we can.
|
|
# At minimum, we want C++/C99-style // comments.
|
|
#
|
|
# Newer versions of compilers might default to supporting C99, but older
|
|
# versions may require a special flag.
|
|
#
|
|
# 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.
|
|
#
|
|
# 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 - this just tests whether the option works and adds it if it does.
|
|
# 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 a compiler
|
|
# that can't be made to support those features, we can add a test to make
|
|
# sure we actually *have* C99 support.
