I met this error earlier this afternoon, and guess that this error happens using new gcc to compile old tigr codes.

at line 860 of Makefile
AM_CPPFLAGS = -Wall -I$(srcdir)/include

the '-Wall' will activate '-Werror=maybe-uninitialized', which make 'make' failed.

Method1: remove '-Wall'
Method2: replace '-Wall' with '-Werror=main'
Both works, but I am sure whether it's safe to do so, as I am not professional on C++.
