Issue: sci-electronics/dsview-1.2.1 fails to compile (CLANG-STRICTER-SYSTEM).
Discovered on: amd64 (internal ref: guru_tinderbox)

NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types
