make / gcc compilation errors on zobject.cpp

[andy289]

Running Fedora 38; recently patched and gcc 13.2.1 20231011. Found 2 issues:

1. Compilations wants to include relic_ec/relic.h which does not exist (got round this) see other posts;
2. 'make' gives following stream of errors building zobject.cpp:

g++ -I/home/andrew/Downloads/openabe/deps/root/include -I/home/andrew/Downloads/openabe/src -I/home/andrew/Downloads/openabe/root/include -I/usr/local/include -std=c++11 -fPIC -DGTEST_USE_OWN_TR1_TUPLE=0 -I/usr/include -DOS_FEDORA_LINUX -pthread -Wall -fstrict-overflow -Wsign-compare -g -O2 -DSSL_LIB_INIT -c zobject.cpp
