config.status: creating config.h
running gmake Makedep... error

Here's the actual patch with what I remember of what it does: Extend sam2p dependency detection script to cope with various new error and warning messages of gcc and clang.

This issue doesn't look prefix specific. Replicated failure in chroot:

checking size of bool... 1
configure: creating ./config.status
config.status: creating Makehelp
config.status: creating config.h
running gmake Makedep... error
configure: error: cannot compute depends

Adjust to changed clang warning message format.

Yes, it's the general problem that ccdep.pl parses compiler messages. Whenever any compiler message changes, it breaks. Prefix on Mac triggers this more readily because clang is the default compiler there.

Upstream is aware of the general issue and has done some work to make ccdep.pl more robust: https://github.com/pts/sam2p/commit/909cbb833ceda9dbbf16c207a51390c7766ed54d.

With 0.49.4 I needed only the attached patch to adjust it to clang-5's changed warning message format.

I haven't reported this upstream yet due to lack of time to put the report together. Could one of you do this?

GCC is used by default nowadays, so this probably is now a different topic
