>Description:
Hello. I'm new to pkgsrc, and I've just bootstraped it in the cygwin environment. When I tried to build some program, almost every packages output this error:
```
ZeeChung@DESKTOP-PI0RAE9 ~/pkgsrc/games/openrct2
$ bmake
ERROR: [depends.mk] Installed package digest-20220214 has an
ERROR:     object format ``PE'' which differs from ``ELF''.  Please
ERROR:     update the digest-20220214 package to ELF.
*** Error code 1
```

>How-To-Repeat:
① Install cygwin. Install basic utils like gcc, make, wget, etc. with cygwin installer.
② Download current pkgsrc branch and bootstrap. You might meet an error of bcrypt.h when compiling libarchive, just turn off HAVE_BCRYPT_H marco and all.
③ Try to compile a program. Almost every packages output the error above.
>Fix:
Maybe simply skip the format checking in depends.mk?
