-----------------------+--------------------
 I had issues with a Cxc cross-compiled toolchain (ARM) on Windows so I
 tried to recompile it natively (there were some updates, GMP is built
 now).

 However, there are issues building newlib related to GMP. The build is
 configured with the following options:

 configure: summary of build options:


   Version:           GNU MP 6.1.0
   Host type:         none-w64-mingw32
   ABI:               standard
   Install prefix:    /c/Users/Robin/Documents/RTEMS/rtems-tools/rtems/6
   Compiler:          x86_64-w64-mingw32-gcc -O2 -g -pipe
 -I/c/Users/Robin/Documents/RTEMS/rtems-
 tools/src/rsb/rtems/build/tmp/sb-197609/6a/c/Users/Robin/Documents/RTEMS
 /rtems-tools/rtems/6/include
   Static libraries:  yes
   Shared libraries:  no

 And the build fails with the following error:


 In file included from ../../../gnu-mirror-gcc-03e2d83/gmp/gmp-impl.h:146,

                  from fib_table.c:4:

 ../fib_table.h:4:1: warning: data definition has no type or storage class

     4 | Error, error, this data is for 32 bits

       | ^~~~~

 ../fib_table.h:4:1: warning: type defaults to 'int' in declaration of
 'Error' [-Wimplicit-int]

 I tried to compile GMP separately, using the following commands:

 ./configure --prefix=/c/Users/Robin/Documents/RTEMS/rtems-tools/rtems/6
 --disable-shared --enable-static
 make
 make install

 And this appeared to work.

 configure: summary of build options:

   Version:           GNU MP 6.1.0
   Host type:         x86_64-w64-mingw32
   ABI:               64
   Install prefix:    /c/Users/Robin/Documents/RTEMS/rtems-tools/rtems/6
   Compiler:          gcc
   Static libraries:  yes
   Shared libraries:  no

 Maybe ABI is not set properly? Also, GMP was alreay (successfully) built
 so I am confused that it is built again as part of the newlib build with
 these settings.

 I am also a bit confused that Host was set to none-w64-mingw32
 because the sb program recognized that the systemis a x86_64 system as
 well (I printed out the value which is assigned to _build to test this in
 the sb program).

 I attached the error report as well

 Kind Regards
 Robin
