You are absolutely right.

Note that, while the test suite cannot be run with the DJGPP build
(because `expect' needs async subprocesses that DJGPP doesn't
support), even if it could be run, the truncated names would work.
That is because, when a program tries to open a file whose name is
pthread_cond_wait.exp, the OS silently truncates that to the 8+3
limits, yielding pthread_.exp and looks for a file by that truncated
name.  That's why we can compile GDB itself (which involves the
compiler, Make, the linker, etc. having to open the source files),
although many of its source files have names in excess of 8+3 limits.
