Summary0014309: CHECK_C_COMPILER_FLAG does not behave like the manpage states
DescriptionThe 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 ReproduceRead the source, Luke (Modules/CheckCCompilerFlag.cmake)
Additional InformationAt least versions 2.8.9 and git HEAD.
