Thanks, builds fine on Win10 with Mingw64 (I ran only ./configure and
make). I get only these warnings:
CCLD make-docfile.exe
CCLD make-fingerprint.exe
In function 'main':
cc1.exe: warning: '__builtin_memcpy' writing 12 bytes into a region of size between 0 and 7 [-Wstringop-overflow=]

I can't tell if they can be ignored or not. This is with gcc 12.1.0.
