Hi Daniel,

the spline code can be found in file splines.c of package 'stats':

https://svn.r-project.org/R/trunk/src/library/stats/src

The file has about 7kbytes size, so the most pragmatic way is to put a 
copy into your own source directory. This is legal as long as your 
derived work will be redistributed under the GPL, too.
