More or less any of this issue pointed out by the compiler is
a coding error. Make sure we flag it and bail loudly.
v2: - apply the change to autotools and scons as well (Emil)
- C++ doesn't need this, it's already an error and the flag
doesn't exist (Gert)

[Emil: apply the same change to autotools and scons]

Emil, I dropped the Android bit as this `-Wno-error` makes it look to me
like they don't want compiler warnings to stop the build.
