C++ and read redefinition

[Daniel R. Hurtmans]

Hello,

I'm using gnulib for quite a long time now to supply missing functions 
(eg: get_opt) in some C++ projects. And suddenly everything breaks down.

Apparently read is redefined to _read when compiling for Windows since 
this September. I'm cross compiling with x86_64-w64-mingw32.

In some classes I'm defining read, write or open members.
After digging in the archive I found the solution of including
#include <unistd.h> before my class header. Fine.

Now I'm facing another problem... since read is now _read it breaks 
pragmas...

Eg using the excellent Armadillo headers library i got this:

...
  /usr/x86_64-w64-mingw32/include/armadillo_bits/arma_forward.hpp: In 
member function ‘arma::state_type::operator int() const’:

/usr/x86_64-w64-mingw32/include/armadillo_bits/arma_forward.hpp:289:26: 
error: expected ‘read’, ‘write’, ‘update’, ‘capture’, ‘seq_cst’, 
‘acq_rel’, ‘release’, ‘relaxed’ or ‘hint’ clause
     289 |       #pragma omp atomic read
...

I'm including <armadillo> after <unistd.h>.
I tried defining GNULIB_NAMESPACE without success.

Any solution would be appreciated? I don't want to be stuck to a 
"pre-September" version.

Thanks,
Daniel
