10 // Typically this done as part of cddefines.h, only required

16 // There appears to be a bug in the POSIX implementation in FreeBSD that was
17 // imported into Apple Darwin (at least version 11.4.2) where defining _POSIX_SOURCE
18 // will cause compilation errors as a result of missing type definitions (e.g., u_int)
19 // when including certain system header files. See e.g. this report:

26 // Cloudy requires C++11, and we specify this using the -std=c++11 compiler flag.
27 // However, cpp versions prior to 6.1.0 have a bug that causes the __cplusplus flag
28 // to have inconsistent values during compilation, causing compilation errors, e.g.
29 // when including <array>. The following hack works around that...
30 #if __cplusplus < 201103

40 // http://www.saii.ull.es/files/doc_intel/doc/HelpMe_FAQ.htm
41 // so we include it here to make really sure that it is in front of
42 // the system includes that may be done before cddefines.h is included
43 //
44 // we define OMPI_SKIP_MPICXX to silence compiler warnings/errors about a
45 // poorly designed C++ interface in openmpi, see this thread for more details:
