Yes, I noticed that as well - other uses of 'unsigned int' are not
causing any problem. I hesitate to change things that aren't causing
problems - often that's a way to create new problems ;)
In BitmapRegion2D.hh I see 4 uses of 'unsigned int' with Log2Bits:
BitmapRegion2D.hh: tnWordIndex = tnBitIndex >> Limits<unsigned
int>::Log2Bits;
BitmapRegion2D.hh: tnBitIndex -= tnWordIndex << Limits<unsigned
int>::Log2Bits;
BitmapRegion2D.hh: tnLastWordIndex = tnLastBitIndex >> Limits<unsigned
int>::Log2Bits;
BitmapRegion2D.hh: tnLastBitIndex -= tnLastWordIndex << Limits<unsigned
int>::Log2Bits;
Are those the same 4 that you needed to change?
For now even the x86_64 systems have 'unsigned int' as 32bits - offhand
I do not know of a (popular) system that has 'unsigned int' being
64bits so it's probably OK to change those 4 uses of unsigned in
to be uint32_t.
