Summary:                    CHECK_C_COMPILER_FLAG does not behave like the
manpage states
Description: 
The manpage states that  CHECK_C_COMPILER_FLAG accepts the same flags as
CHECK_C_SOURCE_COMPILES, but then it overwrites CMAKE_REQUIRED_DEFINITIONS.

So either the manpage is wrong or the implementation is wrong. I found the bug
because I relied on the documented behaviour - I want to have some fixed flags
to be passed to all tests.

Workaround (as of now untested): pass the flag to test plus all the fixed flags
to  
CHECK_C_COMPILER_FLAG

Steps to Reproduce: 
Read the source, Luke (Modules/CheckCCompilerFlag.cmake)

Additional Information: 
At least versions 2.8.9 and git HEAD.
