Hi, When I run make to build pascal 2.0, I get the following error. Would you help me on this ? Thanks in advance. cc -DGPC -DIN_GCC -g -o gpc gcc.o gpc-version.o ../gcc-2.7.2.1/obstack.o `if [ -f "../gcc-2.7.2.1/alloca.o" ]; then echo "../gcc-2.7.2.1/alloca.o" ; else true ; fi` `if [ -f "../gcc-2.7.2.1/mall.c cc: Error: gpc-decl.c, line 2962: In this statement, "((enum tree_code)(((tail)->list.value))->common.code)" is not an lvalue, but occurs in a context that requires one.
