Thanks a lot for patches to Maarten and Jussi. I applied all 4 patches to the 'screen-v4' branch and added you guys to CONTRIBUTORS list.

Also thank to Ben Kamen who tested it (using screen 4.6.2) on its ARM (Xilinx Zynq).

As a followup after 4.3.1 release: this patchset still applies and works with small changes (patch configure.ac instead of configure.in, disable one more AC_TRY_RUN, etc). Thanks Maarten, your work saved quite a bit of time for me.

I'll try to attach the modified patches.

(file #34586, file #34587, file #34588, file #34589)

To be able to cross-compile Screen, two restrictions must be applied to configure script:
- no compiled programs can be run, since they are probably for an incompatible architecture
- no information about the host file system must be used, since that information is not representative of the target

I modified the configure script (configure.in) to take these restrictions into account, see attached patches. I tried to provide sensible defaults for the information that can not be probed when cross-compiling.

Patch 0005 will also affect native builds, but I think it is for the better if Linux is not identified as SVR4. ;)

Note that patch 0003 relies on earlier patches being applied: there are AC_TRY_RUN instances removed by patch 0001 (see bug 43222) and patch 0002 (this bug). If for some reason you don't want to apply those patches, a cross-compile argument would have to be added to those AC_TRY_RUN instances in patch 0003.
