problem building Amaya 9.54 on (ugh) Solaris8

Hi folks:

I am trying to build Amaya on an archaic Solaris system.  I am 
getting an error when running GNU make that goes like this:

/a/perry/data/23/bdsn/Amaya9.54/wxWidgets/src/common/wxchar.cpp
/a/perry/data/23/bdsn/Amaya9.54/wxWidgets/src/common/wxchar.cpp: In function 
`int wxScanf(const wxChar*, ...)':

gmake[1]: *** [baselib_wxchar.o] Error 1

Can anyone tell me what might be the cause?  I searched the archive and did not 
find mention of a problem with the wxchar source.  Thanks.  I'd really like to 
get this to work, at work- I installed Amaya on my Linux partition and my 
Windows partition at home, no worries; and I am quite pleased with it.  But it 
for a large web site at work I maintain that I most need something like Amaya.
