Problem with ncurses-5.3 on Mac OS X 10.2.3 (Darwin 6.3, BSD type unix)

[Gerben Wierda]

When configuring and compiling ncurses-5.3 on Mac OS X 10.2.3, the 
following problem occurs:

cd ../objects;  gcc -DHAVE_CONFIG_H -I../ncurses -I.  -DNDEBUG -I. 
-I../include -I/usr/local/include/ncurses -O2 -no-cpp-precomp -c 
../ncurses/lib_gen.c
../ncurses/lib_gen.c: In function `addch':
../ncurses/lib_gen.c:20: parse error before '%' token
../ncurses/lib_gen.c: In function `addchnstr':
../ncurses/lib_gen.c:27: parse error before '%' token
../ncurses/lib_gen.c: In function `addchstr':
../ncurses/lib_gen.c:34: parse error before '%' token

etc. etc.

looking at lib_gen.c, it seems something goes wrong when it is 
generated:

#undef addch
int addch (const chtype z)
{
% % T ((T_CALLED ("addch(%s)"), _tracechtype2 (0, z))) ; returnCode 
(waddch (stdscr, z)) ;
}

These %-signs probably aren't supposed to be there.

My knowledge of sed and awk is next to nothing, is there someone who 
can help me trace the problem? As TeX Live's release is currently 
waiting for this issue to be resolved (I provide the Mac OS X binaries 
for TeX Live) some urgency is the case.

Thanks in advance,
