Summary:                    check_symbol_exists() fails when "-pedantic-errors"
is added to CMAKE_C_FLAGS
Description: 
Hi,

I just wanted to keep memory of that, the easy workaround is to add
"-pedantic-errors" to more specific variables like CMAKE_C_FLAGS_DEBUG or
CMAKE_C_FLAGS_RELEASE.

Thanks,

Steps to Reproduce: 
Try with this minimal CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
include(CheckSymbolExists)

set(CMAKE_C_FLAGS "-pedantic-errors")
check_symbol_exists(fwrite stdio.h HAVE_FWRITE)

if (NOT HAVE_FWRITE)
  message(FATAL_ERROR "fwrite not available...")
endif()
