compiler option to just compile empty functions

[Frank Winter]

Hello!

This might sound a bit odd. But is there a compiler option to have gcc 
just compiler empty function stubs of all defined functions?

This is just to keep the compiler happy, when compiling another package 
that actually uses the other one.

To explain why I need this. I have to build a package called qdp++ that 
requires libxml2 with a modified version of gcc - spu-gcc.

Unfortunatly the spu-gcc cannot build libxml2. That's not a problem since 
no qdp++ function gets called that require libxml2 functionality.

But the libxml2 calls are spread over the whole qdp++ code. It is nearly 
impossible to comment all those out. So I look for a way to compile just
empty functions of libxml2.

Any suggestions?

Frank
