case sensitive issue with AudioEffectDelay_F32.h ?

[shapr]

I've just tried building the audio pass through example and got this error:

In file included from /home/shae/Arduino/libraries/Tympan_Library/src/Tympan_Library.h:44:0,
		 from /home/shae/Arduino/libraries/Tympan_Library/examples/01-Basic/AudioPassThru/AudioPassThru.ino:14:
/home/shae/Arduino/libraries/Tympan_Library/src/EarpieceMixer_F32.h:6:34: fatal error: AudioEffectDelay_F32.h: No such file or directory

I was able to fix the error by symlinking the lower case name to the upper case name with ln -s AudioEffectDelay_f32.h AudioEffectDelay_F32.h
Does that mean most Tympan development is happening on a case insensitive filesystem?
