All,

PostgreSQL CVS no longer builds cleanly under Cygwin -- although, it
does so under Linux (no surprise). :,)  My plate is full right now.  So,
if anyone would like to help fix the Cygwin build, it would be much
appreciated...

Francisco,

Me neither.

Sorry, but I don't know.

I used the following workaround instead:

    touch src/include/port/win32defs.h

I can confirm the above.

I didn't try the above (yet).

It's just a WAG, but the above smells like missing DLLIMPORTs...

I do not get the above.  However, I get the following instead:

    dllwrap -o plpgsql.dll --dllname plpgsql.dll --def plpgsql.def ...
    fu000001.o(.idata$3+0xc): undefined reference to `_libpostgres_a_iname'
    [snip]
    fu000006.o(.idata$3+0xc): more undefined references to `_libpostgres_a_iname' follow
    nmth000000.o(.idata$4+0x0): undefined reference to `__nm__error_context_stack'
    Info: resolving _error_context_stack by linking to __imp__error_context_stack (auto-import)
    collect2: ld returned 1 exit status
    dllwrap: gcc exited with status 1

Sounds like a missing DLLIMPORT again.

Yup!

The errors from the plpgsql part of your build indicates a potential
problem with your Cygwin setup.  Are you running the latest of the
relevant development tools?

Thanks for the heads up regarding the Cygwin build issues.
