[CMake] An issue with snow leopard?

[Michael Wild]

$ grep -r Wno-long-double cmake-2.6.4
cmake-2.6.4/Utilities/cmcurl/CMakeLists.txt:  CHECK_C_COMPILER_FLAG(- 
Wno-long-double HAVE_C_FLAG_Wno_long_double)
cmake-2.6.4/Utilities/cmcurl/CMakeLists.txt:       
SET(MPRINTF_COMPILE_FLAGS "${MPRINTF_COMPILE_FLAGS} -Wno-long-double")
cmake-2.6.4/Utilities/cmcurl/CMakeLists.txt:       
SET(MPRINTF_COMPILE_FLAGS "-Wno-long-double")

As you can see, -Wno-long-double only shows up in the code that  
compiles the Curl library, and that only if the flag is accepted by  
the compiler (as you can see from the CHECK_C_COMPILER_FLAG). So I  
suspect that this flag is set somewhere in your own CMake code.
