One needs to be aware of the fact that the macros are either 1 or undefined. Currently, #if CYSIGNALS_CXX_ATOMIC will evaluate to true with -fopenmp even if not available.
Also #undef ... is overloaded. In src/cysignals/cysignals_config.h.in it means according to AC_DEFINE: Use the configured value, if available. This is very much different from what #undef ... usually means.
