Some projects failed to compile because its compilation command escalates warnings into errors (e.g., [`bind9`](https://llm-exp.oss-fuzz.com/Result-reports/scheduled/2024-06-21-weekly-all/benchmark/output-bind9-dns_view_asyncload/index.html)). This is particularly problematic for C projects because `JCC` assumes these errors are due to C/C++ compatibility issues and then compiles these projects with `clang++`, which causes different failures that LLM cannot fix (e.g., in `bind9`, the error is caused by other files using C symbols that are not available in C++). This PR removes all flags that may cause this problem in all compilation commands. When tested locally, it fixed the compilation error in `bind9` (with some manual fix on the fuzz target). ---- Here is the command that contains `-Werror*` and causes this problem in `bind9`: ```shell clang -DHAVE_CONFIG_H -I. -I.. -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -DISC_MEM_DEFAULTFILL=1 -DISC_MEM_TRACKLINES=1 -DISC_LIST_CHECKINIT=1 -DISC_STATS_CHECKUNDERFLOW=1 -DDNS_RBTDB_STRONG_RWLOCK_CHECK=1 -DISC_MUTEX_ERROR_CHECK=1 -include ../config.h -I./include -I../include -I../lib/isc/include -I../lib/isc/include -I../lib/dns/include -I../lib/dns/include -I/usr/include/x86_64-linux-gnu -DFUZZDIR=\"/src/bind9/fuzz\" -I../lib/dns -I../lib/isc -I../tests/include -Wall -Wextra -Wwrite-strings -Wpointer-arith -Wno-missing-field-initializers -Wformat -Wshadow -Werror=implicit-function-declaration -Werror=missing-prototypes -Werror=format-security -Werror=parentheses -Werror=implicit -Werror=strict-prototypes -Werror=vla -fno-strict-aliasing -fno-delete-null-pointer-checks -fdiagnostics-show-option -Werror -Wno-vla -O1 -fno-omit-frame-pointer -gline-tables-only -Wno-error=enum-constexpr-conversion -Wno-error=incompatible-function-pointer-types -Wno-error=int-conversion -Wno-error=deprecated-declarations -Wno-error=implicit-function-declaration -Wno-error=implicit-int -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION -fsanitize=address -fsanitize-address-use-after-scope -fsanitize=fuzzer-no-link -I/usr/include/x86_64-linux-gnu -pthread -MT isc_lex_gettoken.o -MD -MP -MF $depbase.Tpo -c -o isc_lex_gettoken.o isc_lex_gettoken.c ``` |
