This article was previously published under Q168934 SYMPTOMS
If you use the /Za switch (Disable Language Extensions) when compiling the
Standard C++ Library headers, it causes multiple compiler errors. For
example:
cl /Za /c /GX /Tp"iosfwd"
Causes the following compiler errors:
iosfwd(132) : error C2906: C++ language change: to explicitly specialize
class template 'char_traits' use the following syntax - template<>
struct char_traits<unsigned short> ...
iosfwd(171) : error C2906: C++ language change: to explicitly specialize
class template 'char_traits' use the following syntax - template<>
struct char_traits<char> ...
Examples of other header files known to cause multiple compiler errors like
C2838, C2146, and C2501 are: <utility>, <iterator>, <xstring>,
<functional>, and <limits>.
RESOLUTION
Do not use the compiler option /Za (Disable Language Extensions) when
compiling the Standard C++ Library headers.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
