Thank you for help.
I DL the watt32s-2.2.11-20141202.tar.gz
unpacked and ran configur.bat
I checked that syserr.c and djgpp.err was generated, so I run make and buuld the libwatt.a [1495960B]
I clean Q2DOS and build again but at the end I got linking error:

wattcp/lib/libwatt.a(pcconfig.o): In function `ReadHosts6File':
h:/source/wattcp/src/pcconfig.c:150: undefined reference to `_w32_ReadHosts6File
'
collect2.exe: error: ld returned 1 exit status
makeo2a.frank:163: recipe for target 'q2.exe' failed
make.exe: *** [q2.exe] Error 1

I can see that in get_xby.h is defined
#define ReadHosts6File    W32_NAMESPACE (ReadHosts6File)
  W32_FUNC void        W32_CALL ReadHosts6File  (const char *fname);
and pccconfig.c:
FUNC_TO_W32CALL (ReadHosts6File)

why W32 prefix?
And when in config.h is 
#undef USE_IPV6        /* Include IPv6 dual-stack support */
why is IP6 function compiled?
