Merge #20195: build: fix mutex detection when building bdb on macOS d0a829e9632379e42f0be5c554e3b692f0d14a95 build: fix mutex detection when building bdb on macOS (fanquake) Pull request description: Starting with the Apple Clang shipped with Xcode 12, [Apple has enabled -Werror=implicit-function-declaration by default](https://developer.apple.com/documentation/xcode-release-notes/xcode-12-release-notes): > Clang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (49917738) This causes bdbs mutex detection to fail when building on macOS (not cross-compiling): ```bash checking for mutexes... UNIX/fcntl configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM. configure: error: Unable to find a mutex implementation ``` as previously emitted warnings are being turned into errors. i.e: ```bash configure:18704: checking for mutexes configure:18815: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -mmacosx-version-min=10.12 --sysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -o conftest -pipe -O2 -I/Users/michael/github/fanquake-bitcoin/depends/x86_64-apple-darwin19.6.0/include -L/Users/michael/github/fanquake-bitcoin/depends/x86_64-apple-darwin19.6.0/lib conftest.c -lpthread >&5 conftest.c:46:1: warning: type specifier missing, defaults to 'int' [-Wimplicit-int] main() { ^ conftest.c:51:2: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration] exit ( ^ conftest.c:51:2: note: include the header <stdlib.h> or explicitly provide a declaration for 'exit' 1 warning and 1 error generated. ``` Append `-Wno-error=implicit-function-declaration` to `cflags` so that `-Wimplicit-function-declaration` [returns to being a warning](https://clang.llvm.org/docs/UsersManual.html#cmdoption-wno-error), and the configure checks succeed. Fixes #19411.
