Hello,
The doc for trunk on the wiki is not updated anymore because on my server, gcc segfaults (famous "ICE") at the end:
I haven't found any 'obvious' reason in the files..

On my desktop computer, with gcc-4.5, there's a different problem:
/home/orzel/hg/eigen/build/doc/snippets/compile_MatrixBase_reverse.cpp: In function ‘int main(int, char**)’:
/home/orzel/hg/eigen/build/doc/snippets/compile_MatrixBase_reverse.cpp:20:20: error: lvalue required as left operand of assignment
make[3]: *** [doc/snippets/CMakeFiles/compile_MatrixBase_reverse.dir/compile_MatrixBase_reverse.cpp.o] Error 1
make[3]: Target `doc/snippets/CMakeFiles/compile_MatrixBase_reverse.dir/build' not remade because of errors.
make[2]: *** [doc/snippets/CMakeFiles/compile_MatrixBase_reverse.dir/all] Error 2
the line leading to error is : "m.reverse()(1,0) = 4;"
I did 'make -k doc' and this is the only problem. No more ICE with gcc 4.5.
