3f17244225 Removed the intrin.h-related part
Removed the commented part as the comment clearly says that VC9 has problems when intrin.h is included.

ca93749614 Support MSVC-7.1/ intrin.h available >= MSVC-8.0
-> MSVC 7.1 has no intrin.h and needs to use "#pragma intrinsic".

Disable explicit operator bool on Oracle C++

if(my_shared_ptr && x)

Fail.  Attempts to wokaround by adding additional operator overloads have so far failed.
