[fpc-pascal]cluster size info for win9x/go32

[Lee, John]

The current fat32 dos routine(from Marco) uses the go32 unit to access dos
memory...so can't see how to access the info in win32 without using a win32
specific algorithm. So any idea what the (simplest) single go32/w32 cluster
size routine would look like...? TIA for any help. PS at the moment the
simplest routine (it's about 7 lines of 100% standard fpc) I have which
works for dos/win9x dos and win32 and linux too, is to write a 5 byte temp
file & check the disk size change- crude but effective! TIA for something
better...John

Wrong ;-). There are some INT21 procedures which are accessible both in 
real and protected mode. FAT32 functions are example of these.
