I thought I'll improve the rebase logic by adding some fixed base
addresses and space to certain apps
(bash, perl, python, rest) to be able to properly rebase the culprit
packages in advance.

I wanted to start with
  /usr/bin/bash.exe
  /usr/bin/cygintl-8.dll
  /usr/bin/cygiconv-2.dll
  /usr/bin/cygreadline6.dll
  /usr/bin/cygncurses-8.dll
starting at -b 0x70000000 -o 0x10000 downwards,
then perl downwards with some reserve,
then python downwards with some reserve,
then fix rebaseall to work with bash and use the new base belowe python,
so that for a rebaseall only the cygwin services have to be stopped.

rebase should omit itself, so that it can be built with cygwin again.
rebase should also support switch -l (list).

But:

/usr/src/rebase-2.4.3-1/imagehelper
$ make -f Makefile.cygwin
g++ -O2     -c -o objectfile.o objectfile.cc
g++ -O2     -c -o objectfilelist.o objectfilelist.cc
g++ -O2     -c -o sections.o sections.cc
sections.cc: In member function `bool Relocations::check()':
sections.cc:288: error: ISO C++ forbids cast to non-reference type
used as lvalue
sections.cc: In member function `bool Relocations::fix()':
sections.cc:331: error: ISO C++ forbids cast to non-reference type
used as lvalue
sections.cc: In member function `bool Relocations::relocate(int)':
sections.cc:366: error: ISO C++ forbids cast to non-reference type
used as lvalue
make: *** [sections.o] Error 1

  for (; (char *)&relocp->SizeOfBlock < (char *)relocs + size &&
relocp->SizeOfBlock != 0; ((char *)relocp) += relocp->SizeOfBlock)
typedef struct _IMAGE_BASE_RELOCATION {
	DWORD VirtualAddress;
	DWORD SizeOfBlock;
} IMAGE_BASE_RELOCATION,*PIMAGE_BASE_RELOCATION;

There's some g++ pointer trickery involved which I cannot solve by my own.
