compile error in LargeFileAccess.cpp on Mac OSX

[Steven Samuel Cole]

I am trying to build exempi 2.1.1 on Mac OSX Snow Leopard.
./configure or ./autogen.sh work ok and seem to produce the same output. 
However, when I run make, I get this error:

make[2]: *** [LargeFileAccess.lo] Error 1
make[1]: *** [all-recursive] Error 1

How can I fix this ?
