I tried to compile openssl 0.9.3a with VC++ 1.52, but until
now I wasn't very succesful. There are many warnings which
are threated as errors, the most eminent one is loss of data
when truncating longs to ints. For example, I fixed
md32_common.h as shown below, but there mare many
places where the same thing happens.
Questions:
- Is this the correct way to fix it? Or should the "len" argument
of HASH_UPDATE simply be changed to an "int". Yes, that
would restrict the block-size to 2^15 for 16-bit compilers but
that is no problem for me.
- Will openssl in the future properly handle 16-bit compiler
support? Or is it simply considered too old.
Regards,
