I am almost  make "hack" for   message/partial
i.e. idea is
(1) to read  full   Content-   string  and look for message/partial, 
total parts and part number. if part number is 0 then handle message as 
usial. Ilse to set  flag  ismessage_partial to  partnumber and aaaa.... 
consider all non-header part as binary
(2) to do (1) is possible at time where we read  from file  but I  found 
that at that point we don't  make unfolding.
(3) unfolding needs  fseek(in,-1, SEEK_SET) that makes problems with so 
called text mode by fopen
This mode is set  with fopen(filename, "r"); than is opposite to binary 
mode "rb"
This "rb"/"wb" is used inOS/2 with number of  compilers exept possible 
emx (gcc), as well as in windows

so I hope to solve message/partial in some days.
