This is due to incompatibilities that arise due to changes in gcc releases.
There seems to be a difference between traditional C and ISO C.
The warning explains it all:
One way to get around this is to change you build environment. Try setting

the variable CC in the make file to one of the below and see if it compiles
fine.
gcc -ansi -Wall -pedantic
gcc -traditional -Wall -pedantic
Another way would be what my debian is able to do for me:
# gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
# apt-get build-dep gcc-3.3
