Fixed! MSVC does not like brackets when defining default parameters
for templates. I needed to change
template<typename MatrixType, int BlockRows=Dynamic, int BlockCols=Dynamic,
int _DirectAccessStatus =
(ei_traits<MatrixType>::Flags&DirectAccessBit) ? HasDirectAccess :
NoDirectAccess> class Block;
to
template<typename MatrixType, int BlockRows=Dynamic, int BlockCols=Dynamic,
int _DirectAccessStatus =
ei_traits<MatrixType>::Flags&DirectAccessBit ? HasDirectAccess :
NoDirectAccess> class Block;
I tried to circumvent this with a ei_meta_int_if (like ei_meta_if but
with enums) but that does not work either! I hope we don't break any
other compiler, otherwise this forward declaration needs to be put in
its own MSVC guarded path.
