Compilation failure if directory too long

[kufupa]

Spent about an hour trying to understand why moving a portable arduino install compiles in some folders but not others. To recreate - keep putting install in more and more folders until the basic file, with no code inside setup() or loop() procedures, has a compilation failure.

ERROR LOG:

Changing name from akjdhfjkldshfdafgaastmlink_template to aastmlink_template compiles just fine.
