After this commit, 32bit build failes with:
/usr/lib/gcc/i686-pc-cygwin/9.3.0/../../../../i686-pc-cygwin/bin/ld:
dumper.o:/home/yano/newlib-cygwin/i686-pc-cygwin/winsup/utils/../../.././winsup/utils/dumper.cc:295:
undefined reference to `NtQueryVirtualMemory'
This seems to be solved with the patch:
