No. The whole case sensitivity handling in the compiler is pretty  
broken by design currently, as it's hardcoded per OS based on the  
most common situation under said OS and not configurable in any way  
(although most OSes nowadays support case insensitive, case-aware and  
case-sensitive file systems).

Your issue is caused by the implementation of a directory cache in  
the compiler since 2.0.4, which for systems defined as case-aware did  
not keep track of the original file name casing. Your issue is  
probably fixed/worked around in 2.3.1, but that change will not be  
merged back to 2.1.5, because it was quite invasive. It will however  
be in 2.2.2
