Bug ID: 19264
Summary: -fms-compatibility should always emit 'extern inline'
functions and give them weak_odr linkage
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Frontend

Blocks: 13707, 18887
Classification: Unclassified
MSVC always instantiates "extern inline" functions. Furthermore, prior to the
addition of /Zc:inline, it would never discard the separate instantiation of
the inline function, so the symbol would always be available for use from
another translation unit.
This is actually used by _AtlInitializeCriticalSectionEx. The intention
appears to be that the user of the library should include this header, and then
the ATL will pick up the definition from the user's object files.
I believe this was the cause of link errors when building nacl64.exe in
Chromium.
