problem with building pandas - not using gcc as compiler
"""the example is merely
pip install pandas - which fails, so download and run

python ./setup.py build

```
I fear it is a specific behavior of gcc compared to not gcc/gnu 'features' (aka NGNU for 'Not "GNU Not Unix"')

I will attach the .cpp, as well as a .i (-E) output, as well as verbose include file processing (.info file)

The build stops with the following messages:

reading carefully - it comes down to errors while processing these four lines:
  +468  static const execute_fn unpack_construct = &unpack_execute<true>;
  +469  static const execute_fn unpack_skip = &unpack_execute<false>;
  +470  static const execute_fn read_array_header = &unpack_container_header<0x90, 0xdc>;
  +471  static const execute_fn read_map_header = &unpack_container_header<0x80, 0xde>;

These become (from the .i file)
#line 468
static const execute_fn unpack_construct = &unpack_execute<1>;
static const execute_fn unpack_skip = &unpack_execute<0>;
static const execute_fn read_array_header = &unpack_container_header<0x90, 0xdc>;
static const execute_fn read_map_header = &unpack_container_header<0x80, 0xde>;
#line 314 "pandas/msgpack/_unpacker.cpp"

And - whether it is pandas or perhaps cython - my knowledge of C does not understand how:
&unpack_execute<1> and &unpack_execute<0>
are useable against:

static inline int unpack_execute(unpack_context* ctx, const char* data, size_t len, size_t* off)

FYI: _packer.cpp is fine.

Will try again to attach file - getting message "We don't support that file type", even after putting them into a zip file.
