OS/2 warnings

[abwillis]

There are a couple warnings when building with (about protmode and emx DLLs) and one with open watcom.

Where are you seeing the PROTMODE warnings? I have compiled with gcc 4.4, VAC 3.6 and OpenWatcom? 1.9 and did not see any warnings about PROTMODE. I had noticed the watcom warning about the missing const... but when I added const the other compilers complained...

Not going to be able to get all of the warnings gone with all the compilers without really mangling the code up... (VAC complains about tons of stuff it shouldn't) ... but I can commit the spawnvp() change if it is bothering you. :)

The protmode warnings (The PCCH warnings are new since this last svn pull): os2/dw.c:1516: warning: pointer targets in passing argument 3 of 'WinDrawText?' d iffer in signedness U:/USR/include/os2emx.h:5888: note: expected 'PCCH' but argument is of type 'cha r *' Warning! W1058: file ldIoGVmZ.: line(17): protmode option not valid for an OS/2 EMX dynamic link library

I am setup to use wlink instead of ilink but not sure if that would make the difference if you don't get the warning.

[bsmith]

Yeah I knew that WinDrawText?() code was going to cause a warning when I was writing it... just forgot to add the typecast before I committed it...

Regarding that protmode warning that is definitely being generated by wlink... I use ilink 5.0 to link... not sure where I got it from it was a long time ago... but I think it is newer than what came with VAC 3.6.

I've been reading a bit to see if that line is necessary or why I had it in there... I originally wrote this code over a decade ago and I can't remember why I did some things... or if it was just cut and paste. ;)

[bsmith]

Ok so... I just committed fixes for these two warnings in addition to several other warnings... and a likely calling convention problem with Watcom in the print code.

For now I just removed the protmode statements like you suggested, if it causes problems I can revert it or reevaluate the solution later.
