No. IMO, the above is not relevant to the Cygwin fork()/rebase issue.
Note that the "-mdll" flag is used when building Win32 Python shared
extension modules with Cygwin gcc in "-mno-cygwin" mode -- not when
building Cygwin Python shared extensions.
BTW, Cygwin fork() has rebase issues with Apache, Perl, etc. too.

The above is the expected behavior. When the entire Python regression
test is run, the probability of a DLL base address conflict is much
higher than when individual regression tests are run separately.

Hi Jason
I just did a quick test compilng a ~month old CVS version
of Python after making the following change in distutills.cygwincompiler
# Hard-code GCC because that's what this is all about.
# XXX optimization, warnings etc. should be customizable.
self.set_executables(compiler='gcc -mcygwin -O -Wall',
# compiler_so='gcc -mcygwin -mdll -O -Wall',
compiler_so='gcc -mcygwin -shared -O -Wall',
linker_exe='gcc -mcygwin',
# linker_so=('%s -mcygwin -mdll -static' %
linker_so=('%s -mcygwin -shared' %
self.linker_dll))
and the following (3) modules had the remap error for cygssl.dll
when run from inside the test-suite
test_fork1.py
test_popen2.py
test_pty.py
but ran successfully when run directly
HTH
