Fix some compiler warings from msvw in add-patch.c for value truncation
form 64 bit to 32 bit integers.Change unsigned long to size_t for
correct variable size on linux and windows.
Add macro strtos for converting a string to size_t.
Test if convertion fails with over or underflow.
Signed-off-by: Sören Krecker <soekkle@xxxxxxxxxx>
Uses strtouq
impove linux support
Change Macro name
