undefined reference to twitCurl::~twitCurl()

```
What steps will reproduce the problem?
1. Download twitterClient_SRC2.zip
2. Get libs/libcurl.lib and libs/twitcurl.lib
3. Link this to a project in Code::Blocks (Project - Build options - Linker
settings)
4. Try to compile a program in Code::Blocks (using GNU GCC Complier)

What is the expected output? What do you see instead?
||=== twittout, Release ===|
obj\Release\main.o:main.cpp|| undefined reference to `twitCurl::twitCurl()'|
obj\Release\main.o:main.cpp|| undefined reference to `twitCurl::~twitCurl()'|
||=== Build finished: 2 errors, 0 warnings ===|

What version of the product are you using? On what operating system?

Reproduce the report by opening twitterClient_SRC2.zip, linking libs/libcurl.lib and libs/twitcurl.lib in Code::Blocks, and compiling the example with GNU GCC on Windows. Start with main.cpp and the listed linker errors for twitCurl::twitCurl() and twitCurl::~twitCurl(); done means the reported undefined references no longer occur during compilation.
