can't rename mysql table

Question

I'm trying to rename my table using this SQL. I'm using MySQL 5.1.41 on Windows XP.

USE 'bobby_tables';

    ALTER TABLE gc_acompte_fournisseur
      RENAME TO GC_Acompte_Fournisseur;

And the query claims to have executed correctly, but it lies! My table name is still all lower case!

What foul arcanery have I run afoul of that forbids me from capitalizing my tables?
