undefined referenced to 'gdStringFTCircle'

Hi,

I found An ERROR in your website

in the manual of "Font and Text Handling Functions"

the example in the function explaination "gdImageStringFTCircle"

line 26.

the name of function "gdImageStringFTCircle" is wrote by "gdStringFTCircle" !!!!!

I have complie this source code for a day , my complier keeps saying "undefined referenced to 'gdStringFTCirlce'

I spent my whole day to re-install my gdlib ,pnglib,freetype and even zlib!

Hope you modify this source code as soon as quickly since I don't know how many people have been "ANNOYED" by this "little" mistake.
