Compile error with libmemcached

[TV Ganesh]

Hi,
    I am having a basic error when trying to use the gcc compiler to
compile the code user the tests folder. I get the error
error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘*’
token. The offending code is the 'const' keyword.  Please let me know
if I have to use any special flag for const, bool keywords. I have
used std=c99 but I get the error.

I know this is too fundamental an error but any help will be
appreciated. Have done a fair amt of googling but of no help.

Thanks
Ganesh
