Question: warnings relevance

Hi,
This is only an amateur's curiosity: how relevant are warnings like
this? Building on VC++ 2008 express
1>..\..\src\text\fmt\xp\fl_BlockLayout.cpp(7131) : warning C4146: unary
minus operator applied to unsigned type, result still unsigned

1>..\..\src\text\fmt\xp\fl_DocLayout.cpp(913) : warning C4244:
'initializing' : conversion from 'double' to 'UT_sint32', possible loss
of data

1>..\..\src\text\fmt\xp\fl_FrameLayout.cpp(192) : warning C4244:
'argument' : conversion from 'double' to 'UT_sint32', possible loss of data

etc...
