[ECOS] i2c driver complie error

["liu hua" <rongye_liu at hotmail dot com>]

I need help for i2c driver.

In my project,I use the PCA9564 (I2C bus controller). So,I will write a 
driver for PCA9564. I download the I2C driver code from eCos CVS server,and 
write a test driver i2c_pca9564.c. This driver use the code from I2C doc 
file. But,when I complie the eCos with configtool,there are some compile 
error:

Can you tell me what error are in my driver?
