You used a Win32 unzip utility instead of a DOS based one.

Windows NT has two APIs - a native Win32 API which supports long file
names - and a virtual DOS machine which supports DOS interrupts.  DJGPP
applictions are DOS API.  Microsoft chose to not provide long name support
for DOS applications.  So "dir" uses Win32 calls - sees long names.
"ls" is a DJGPP application and only sees short names because that's all
Microsoft decided to allow.  The ntlfn08b.zip distribution contains a
cool workaround/fix for this problem to support the DOS long name API
under Windows NT, which makes it behave like Windows 2000 (but with
fewer bugs than Windows 2000...)
