failed make with gcc 3.2.2 and flex 2.5.31

[Bryan Koschmann - GKT]

Hello,

Just did a fresh install of Slack 9.0. I removed flex 2.5.4a and upgraded
with source to 2.5.31. I tried the latest tarball of lilypond with no
luck, and tried a cvs version from last night. When doing a make it dies
with this:

make[2]: Leaving directory `/usr/src/lilypond/flower/include'
make[1]: Leaving directory `/usr/src/lilypond/flower'
make[1]: Entering directory `/usr/src/lilypond/lily'
rm -f ./out/includable-lexer.dep;

If you could provide any help it would be great. With the tarball version
I tried the patch in the directory, and various others from maillist
archives (each after deleting and untarring a new lilypond).

Thank you in advance!
