Unresolved reference in a cygwin/xfree86 library

[Claudio Beccari]

I tried to install LyX on a laptop that has a US keyboard; I had to 
download and install cygwin and Xfree86 plus customize for my terminal. 
Everyting OK; Installed LyX; everything OK except for one point.

For writing in Italian I need the grave accent (the acute is comparatively 
rarer and it works fine) and I want ot set it up the same as in MSWord (and 
SciWord, apparently); I customize the cua.bind LyX binding file in order to 
have accents configured as a <Ctrl>-accent combination followed by the 
suitable vowel. Things work fine for ', ~, and ^; they dont work with " and 
`. I can do without the umlaut, but I can't do without the grave accent.

I read and reread the LyX documentation; it suggests to configure the 
keyboard key by means of  xmodmap and xkeycaps; xmodmap is part of 
cygwin/xfree86 distribution (the latest distribution downlaoaded -- for the 
n-th time -- on 25 july 2002) and apparently indicate that my laptop 
keyboard is correctly identified and installed. Nevertheless since things 
don't work as expected, I have the curiosity of installing xkeycaps; I 
downloaded it from its home site (www.jwz.org) and followed the whole 
procedure for the installation which implies using xmkmf, make, and so on; 
the former works fine, the latter stops with a linker error on the very 
last step, where it say that it found and unresolved reference 
XpmReadFileToPixmap in a module deriving from the compilation of pixmap.c 
in library /usr/X11R6/lib/libXaw.a.

I suppose that libXaw.a has a little glitch, but may be it's only my 
installation.

Any suggestion?

Thanks in advance
