+** Cygwin build of Emacs hangs after rebasing Cygwin DLLs
+
+Usually, on Cygwin, one needs to rebase the DLLs if an application
+aborts with a message like this:
+
+ C:\cygwin\bin\python.exe: *** unable to remap C:\cygwin\bin\cygssl.dll to
+ same address as parent(0xDF0000) != 0xE00000
+
+However, since Cygwin DLL 1.5.17 was released, after such rebasing,
+Emacs hangs.
+
+This was reported to happen for Emacs 21.2 and also for the pretest of
+Emacs 22.1 on Cygwin.
+
+To work around this, build Emacs like this:
+
+ LDFLAGS='-Wl,--enable-auto-import -Wl,--enable-auto-image-base' ./configure
+ make LD='$(CC)'
+ make LD='$(CC)' install
+
+This produces an Emacs binary that is independent of rebasing.
+
+Note that you _must_ use LD='$(CC)' in the last two commands above, to
+prevent GCC from passing the "--image-base 0x20000000" option to the
+linker, which is what it does by default. That option produces an
+Emacs binary with the base address 0x20000000, which will cause Emacs
+to hang after Cygwin DLLs are rebased.

** Interrupting Cygwin port of Bash from Emacs doesn't work.
Cygwin 1.x builds of the ported Bash cannot be interrupted from the
