cmake: clean OtherTests, fixing -Werror
There were several -Wunused warnings and one duplicate macro definition. The EXTRA_DEFINES variable of the CurlCheckCSources macro was being abused ("__unused1\n#undef inline\n#define __unused2", seriously?) to insert extra C code. Avoid this broken abstraction and use cmake's check_c_source_compiles directly (works fine with CMake 2.8, maybe even cmake 2.6). After cleaning up all related variables (EXTRA_DEFINES, HEADER_INCLUDES, auxiliary headers_hack), also remove a duplicate add_headers_include macro and remove duplicate header additions before the struct timeval check. Oh, and now the code is converted to use CheckCSourceRuns and CheckCSourceCompiles, the two curl-specific helpers can be removed. Unfortunately, the cmake output is now slightly more verbose. Before: Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test) Performing Test int send(int, const void *, size_t, int) (curl_cv_func_send_test) - Failed Since check_c_source_compiles prints the varname, now you see: Performing Test curl_cv_func_send_test Performing Test curl_cv_func_send_test - Failed Tested: int send(int, const void *, size_t, int) Compared cmake output with each other using vimdiff, no functional differences were found. Tested with GCC 4.9.1 and Clang 3.5.0. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
