When the field test C++ compiler became available I attempted to build 
my MariaDB v5.5 kit.  It was a no go for a few reasons.

One,
The field test is still limited in some functionality.  For example, 
there are some pragmas that are not yet supported or not yet fully 
supported.  The include_directory pragma does not yet appear to work and 
my build procedure depends heavily on this.

Two,
There are a number of places in the port that assume that long and 
size_t are 32 bits.  For x86_64, they are 64 bits.  Addressing this 
would almost mean redoing the port. (I think long is a bigger issue than 
size_t).

Three,
In order for the headers included with the compiler to compile 
correctly, certain values must be defined.  For example, in order to use 
string.h, either __CORRECT_ISO_CPP_STRING_H_PROTO or 
_STRING_H_CPLUSPLUS_98_CONFORMANCE_ must be defined.  Otherwise, the 
compiler throws errors and aborts.  I did not see anything about this in 
the documentation and stumbled across it when trying to figure out why 
the errors were occurring.  Now I wonder if there are others.

I think MariaDB, either V5 for V10, will have to wait until the C++ 
compiler is more complete.
