Sorry: am a cygwin newbie. I read /usr/doc/Cygwin/rebase-2.2.README and
noted that there are some parameters I need to supply to rebaseall ? or to
rebase itself ? Is there a way to figure out how to do this ? I use
cygcheck to check which dlls I am using, and its output is:

euclid 2:04pm [3d_diameter]> cygcheck main
Found: .\main.exe
main.exe
  C:\WINDOWS\System32\msvcrt.dll
    C:\WINDOWS\System32\KERNEL32.dll
      C:\WINDOWS\System32\ntdll.dll
  C:\WINDOWS\System32\GLU32.DLL
    C:\WINDOWS\System32\OPENGL32.dll
      C:\WINDOWS\System32\ADVAPI32.dll
        C:\WINDOWS\System32\RPCRT4.dll
      C:\WINDOWS\System32\GDI32.dll
        C:\WINDOWS\System32\USER32.dll
      C:\WINDOWS\System32\DDRAW.dll
        C:\WINDOWS\System32\DCIMAN32.dll
  C:\cygwin\bin\glut32.dll
    C:\WINDOWS\System32\WINMM.dll

I am guessing that the main dlls I am concerned with are:

glut32.dll
glu32.dll
opengl32.dll
