Unfortunately, the build system hides compiler flags, and they are 
crucial for understanding what happened here.

Apparently tests are compiled with "private" redefined as "public":

bin_test_all_CPPFLAGS = -Dprotected=public -Dprivate=public -DJSON_IS_AMALGAMATION=1

This breaks the <sstream> header:
