simple c program hello world not work in mandrake8

[eric]

Dear gnu glibc programmers:

  I download and install gcc3.0.3 from gnu ftp site, by ./configure,
make, make install
they try my hello world in printf("hello world"), it still not print out
if no \n at the end.  Probably it is caused by shell(some told me)

  I also tried to load libstdc++-v3.0.95 , but have difficult to install
it
./configure not work  for 3.0.3
  so I went to rpm find to get mdk's libstdc++ and isntall it.

still not work,  

  is that a bug in glibc, if it is would you mind to tell me where and
which lib I should download to install to fix it.

highly appreciate your help, sincere eric,
