Description
The has_argument and get_supported_argument methods are reporting success when the compiler returns an unsupported flag error to stderr.
I have attached a simple test case which demonstrates the error. The relevant meson.log entry is
Running compile:
Working directory: /tmp/tmpygkykj04
Command line: c++ /tmp/tmpygkykj04/testfile.cpp -pipe -D_FILE_OFFSET_BITS=64 -c -o /tmp/tmpygkykj04/output.obj -O0 -fpermissive -Wdeclaration-after-statement
Code:
int i;
Compiler stdout:
Compiler stderr:
cc1plus: warning: command line option '-Wdeclaration-after-statement' is valid for C/ObjC but not for C++
Compiler for C++ supports arguments -Wdeclaration-after-statement: YES

Research direction
Start by locating the implementations of compiler.get_supported_argument and has_argument, then reproduce the attached test case and inspect the corresponding meson.log output. Done means a compiler response reporting the flag as unsupported is no longer reported as supported.
