When I looked into this, I went with a slightly different approach.
Instead of copying from ncurses, I generated the arrays from term.h
and an awk script.
awk '
/TICODE_[a-z]+,/ {
names[++numnames] = substr($1, 8, length($1) - 8)
}
/^#define t_[a-z_]+(t)/ {
fnames[++numfnames] = substr($2, 3, length($2) - 5)
}
END {
print "const char *const strnames[] = {"
for (i = 1; i <= numnames; ++i)
print("\t\"" names[i] "\",")
print "\t(void *)0"
print "};"
print "const char *const strfnames[] = {"
for (i = 1; i <= numfnames; ++i)
print("\t\"" fnames[i] "\",")
print "\t(void *)0"
print "};"
}

You don't need to include the whole names.c in term.h, just declare the arrays:
diff --git a/libterminfo/term.h b/libterminfo/term.h
index 884cfe9..8345a7f 100644

I can confirm the issue here. No idea about how to solve it though.
Compared to ncurses, I also notice a bit of flickering when scrolling
fast (status bar occasionally blinks). I remember this problem being
more severe back when I looked into this, so I had decided to stick
with ncurses for oasis for the time being.
