Chapter10 oit example outputs errors on Linux

What steps will reproduce the problem?
1. make and run the Linux/Chapter10/oit example
2. Errors are printed on the console and the opened window is blank.

Linux/Chapter10/oit$ ./oit 
The shader at basic.vs failed to compile with the following error:
0(16) : error C5060: out can't be used with non-varying vFragColor
0(17) : error C5060: out can't be used with non-varying vTexCoord

The shader at basic.vs failed to compile with the following error:
0(16) : error C5060: out can't be used with non-varying vFragColor
0(17) : error C5060: out can't be used with non-varying vTexCoord

A GL Error has occured : 1281
A GL Error has occured : 1281
A GL Error has occured : 1281
...

On adding the "varying" keyword to vFragColor and vTexCoord, as well as fixing 
the same in other shaders, we run into this...

Linux/Chapter10/oit$ ./oit 
The shader at oitResolve.fs failed to compile with the following error:
0(7) : warning C7532: global type sampler2DMS requires "#version 150" or later
0(7) : warning C0000: ... or #extension GL_ARB_texture_multisample : enable

literals

The shader at msResolve.fs failed to compile with the following error:
0(9) : warning C7555: 'varying' is deprecated, use 'in/out' instead
0(14) : error C1008: undefined variable "textureSize2DMS"

A GL Error has occured : 1281
A GL Error has occured : 1281

3. I tries searching "textureSize2DMS" method on google, and the only place the 
word seems to occur is in this code. Is this a typo?

What version of the product are you using? On what operating system?
Ubuntu 10.04, Nvidia drivers.

Please provide any additional information below.
I am guessing many of these errors occurred because of some deprecation that 
has happened since the book was written. But I am really surprised to find no 
mention of textureSize2DMS on the internet, except the few examples in this 
book. Am I missing something very obvious here?

Any help would be appreciated.
