OK. Committed as posted (in one lump), with the following change log
2009-10-06 Charles Wilson <...>
Additional pseudo-reloc-v2 support
* ntdll.h: Add custom NTSTATUS value for pseudo-reloc
* pinfo.cc (status_exit): Map custom pseudo-reloc
error value STATUS_ILLEGAL_DLL_PSEUDO_RELOCATION to 127.
* sigproc.cc (child_info::proc_retry): Return exit code when
Cygwin modifications to pseudo-reloc.c
* lib/pseudo-reloc.c: Added comments throughout and various
whitespace fixes. Exploit cygwin_internal(CW_EXIT_PROCESS,...)
for fatal error handling that is consistent with cygwin process
life-cycle. Ensure state variable (in _pei386_runtime_relocator)
is unique to each address space, across fork().
(__print_reloc_error): New function for reporting errors in a
manner supported by cygwin at this early stage of the process
(_pei386_runtime_relocator): Ensure relocations performed
only once for each address space, but are repeated after fork()
in the new address space.
only once for each address space (e.g. across fork()).
(__write_memory) [MINGW]: Ensure that b is always initialized
by call to VirtualQuery, even if -DNDEBUG.
* lib/pseudo-reloc.c: Import new implementation to support
v2 pseudo-relocs implemented by Kai Tietz from mingw.
