Hi Hans,
The easy fix to this is use Watcom 1.2.
The current versions are 1.7 and 1.8 release candidate,
where and why would one download a years-old OW 1.2...?
I must say that the kernel compiled well with OW 1.3 of
2004, but I wonder whether newer versions work better.
I use latest version of Open Watcom and NASM 0.98

The filesize variable is a pointer to unsigned 32 bit integere here.
The theseg variable is unsigned 16 bit integer here. Which versions
of OpenWatcom expect which _dos_allocmem parameter types? It seems
plausible to use 16 bit segments if you ask me...
Do both OpenWatcom 1.7 and 1.8 complain? Maybe a regression?

1078 #if defined __WATCOMC__ || defined _MSC_VER
1079 _dos_getftime(fdin, filetime-date, filetime-time);
1080 #elif defined __TURBOC__
1081 getftime(fdin, filetime);
1082 #endif
This is related to:
160 #ifdef __TURBOC__
161 typedef struct ftime ftime;
162 #else
163 typedef struct
164 {
165 unsigned short date, time;
166 } ftime;
167 #endif
It seems newer OpenWatcom versions like using int a lot, but why?
Since when is this the case? Do you know a macro for making the
line 165 depend on the version of OpenWatcom? Or maybe better, is
there a header file which makes using _dos_getftime / _dos_setftime
easier, if possible version independent in OpenWatcom?
