To be able to return free space on larger non local disks, the redirector
needs an extension. Dosemu2 has implemented this function and FDPP
has an almost identical patch to this. If the extension is not
implemented by your chosen redirector, then fallback to the standard
110c function is done for int21/7303.
With this patch up to 2TB (with Dosemu2 reporting in 512 blocks) can be
displayed.
Also adds a CheckDebugger byte to the CONFIG block and
support for reading and writing this setting in the
SYS CONFIG program. Default is 0 (no check assume absent).
correct I186 and I386 macros definition to work with all Open Watcom toolchain versions
command line definition macro has "1" value but in header file it is defined as blank value
anyway I86/I186/I386 macros usage is not transparent, it is definition duplicity in header file and on command line
it is wrong solution even if it works on most of compilers (command line macro re-definition is hidden)
GCC has -mrtd but the args are pushed in reverse versus PASCAL. So asm
routines have to use macros to obtain the stack arguments.
For the complex call_nls assembly, revert the arguments in C using a
preprocessor macro.
