<pre>When building test_process.exe in chrome (as of
ec4400b28a913290681684212c9dfccb5ea103ed, July 31, 2018) the command-line
passed to the linker contains /SUBSYSTEM:CONSOLE,5.02 but test_process_main.cc
contains this entry point:
int APIENTRY wWinMain(HINSTANCE, HINSTANCE, wchar_t*, int)
link.exe honors the command-line switch and gives a link error. lld seems to
ignore the command-line switch and generates a binary. It is not clear whether
it looks at the Windows version information in the /SUBSYSTEM switch.
This was reported in crbug.com/869503.
The consequences of this difference of behavior is that binaries that build
with lld-link.exe may fail to link with link.exe and these failures will be
mysterious. It also suggests that if two entry points are compiled in and one
is chosen using the /SUBSYSTEM flag then that may fail with lld.
This is not a critical bug but it should be fixed in order to avoid confusing
incompatibilities.</pre>
