libfuse won't compile on 7.2 without a patch. Attached is a working fuse patch. Drop in /spksrc/cross/fuse/patches/

003-closefrom-glibc.patch

For example borgbackup :

$ make arch-denverton-7.2 -C ./spk/borgbackup/

[hgy59]

In #6717 the build of cross/cpulimit was fixed for DSM 7.2 and SRM 1.3

DSM 7.2 and SRM 1.3 toolchains are lacking the header files sys/sysctl.h and bits/sysctl.h

[hgy59]

cross/tcp_wrapper fails to build for DSM 7.2 and SRM 1.3

several warnings and finally

percent_m.c:32:25: error: ‘sys_nerr’ undeclared (first use in this function)

The following packages depend on tcp_wrappers

• sslh
• stunnel
