Salut � tous,
Comme me le demande Bruno, voici en pi�ce jointe l'int�gralit� du
fichier html_tbl.c.
Pour r�pondre � tes 2 autres questions, je suis sous i386. Enfin,
voici l'adresse du site o� j'ai t�l�chaqg� l'appli:
http://atrey.karlin.mff.cuni.cz/~clock/twibright//links/download
Merci beaucoup de votre aide et � bient�t.
