- cmake: sync `-ftree-vrp` behavior with autotools. - build: enable `-Wjump-misses-init` for GCC 4.5+. Credits-to: Marcel Raad - packet: fix `-Wjump-misses-init` warnings. ``` src/packet.c: In function ‘_libssh2_packet_add’: src/packet.c:671:9: error: jump skips variable initialization [-Werror=jump-misses-init] src/packet.c:920:31: note: ‘want_reply’ declared here src/packet.c:671:9: error: jump skips variable initialization [-Werror=jump-misses-init] src/packet.c:919:26: note: ‘len’ declared here src/packet.c:669:9: error: jump skips variable initialization [-Werror=jump-misses-init] src/packet.c:1121:31: note: ‘want_reply’ declared here src/packet.c:669:9: error: jump skips variable initialization [-Werror=jump-misses-init] src/packet.c:1120:26: note: ‘len’ declared here src/packet.c:669:9: error: jump skips variable initialization [-Werror=jump-misses-init] src/packet.c:1119:26: note: ‘channel’ declared here ``` - build: enable gcc-12/13+, clang-10+ picky warnings - acinclude.m4: sync formatting/comments with curl. - autotools: fix `-Wtrampolines` picky warning for gcc 4.x versions. Follow-up to 854cfa8292d251d2133ff41b9fc2e232ab200a9c #1524 - cmake: enable `-Wall` for MSVC when `PICKY_COMPILER=ON`. - MSVC: fix `-Wall` warnings. Seen on VS2015. Not seen on VS2022. Unknown for other versions. ``` tests\test_simple.c(60): warning C4777: 'fprintf' : format string '%d' requires an argument of type 'int', but variadic argument 1 has type 'std::size_t' tests\test_simple.c(60): warning C4777: 'fprintf' : format string '%.*s' requires an argument of type 'int', but variadic argument 2 has type 'std::size_t' ``` - mbedtls: stop silencing warnings in 3rd-party header. Follow-up to a3aa6b4ca83bb8a3ed159612a44b25261dc9f537 #1525 - cmake: stop deleting `-W<n>` from `CMAKE_C_FLAGS` (MSVC) 1. `CMAKE_C_FLAGS` may apply to other projects, and deleting/altering it may be unexpected. 2. We pass `-W4`/`-Wall` internally now, which do override custom `-W<n>` options as tested with VS2008 and newer VS generators. Closes #1588
