Re:GMP error when building aarch64-rtems-gcc on Mingw64

[jameszxj]

It has been there for a while. It is caused by the gmp configure parameter 
(in gcc/makefile.in line 12644 )


I change "--host=none-${host_vendor}-${host_os} 
--target=none-${host_vendor}-${host_os}"
to "--host=${host_alias} --target=${host_alias}", the building succeeds.

Subject:&nbsp;GMP error when building aarch64-rtems-gcc on Mingw64



While building gcc, arg3nexwm1 fails. The error follows

This is due to GMP_NUMB_BITS not being equal to 32. Has anyone 
encountered this?

Thanks,

Ryan
