i didn't make them... someone else did to help me with compiling on OS/2 with
EMX... i will have to dig back into my saved messages to locate what they sent
me and who it was... basically all they did was to add a few $IFDEF for OS/2...
they also created one pas file with some initialization routines...
i can send what i have but i don't know where to send to... plus, these are only
the 4 or 5 files that my one project needed for mime translation stuffs...

hummm... i'm hoping that i won't run into a wall with this :/

ahh... all i know is that they were referenced as being needed for accessing
https sites... without them, even with one of the specified ssl plugins, ssl
still wouldn't work...

cool! that may be what i'll need to use... that plus whatever code changes to
synapse to load them... i do not recall if synapse has any OS/2 related defines
or code... i don't recall seeing any notation of such in the docs or synapse
code that i've looked at... everything seems to only state windows and linux...
maybe one of the first things to do is for me to get the files and extra init
code to someone who knows what they are doing and then let's see if one can get
all of synapse to compile on OS/2 with FPC by starting off with the blcksock unit...

currently, all my FPC compiles are configured to use EMX because that's what i'm
familiar with... i do have those libc files for a couple of other tools, though...

i think i understand... i'll sleep on it and see if a fully grok it on the
morrow after i get up...
> Hope this helps
it beats sloughing thru it all getting it to work with the barest of examples
like i've been having to do... the docs are ok telling what something does but
there are no example in the docs on how to do or use the routines... one such
example is a note about having to prepare the POST vars and contents the same
way one would prepare them for a GET but no where was anything offered that
actually showed such... i took a wild guess and came up with a routine that
works... it is based on storing the var names and their values in two arrays and
then counting thru them but if i had no clue how they were supposed to be formed
in the first place... well...
