You can't have that, the check is correct.  There are filesystems (NTFS 
for instance) that are case-preserving but case-insensitive, on those you 
really can't have two files that differ only in casing.  You need to find 
a different solution, either consistently use .cc instead of .C, live with 
the inconsistency or rename the base name of these files.


Ciao,
