Hi again,

Once we solve the zlib issue, I might need help with statically linking 
with libstdc++.  According to cygwin's gcc-4 documentation, this is 
supposed to be possible:

"By default, user applications will be linked against these DLLs unless 
the option '-static' is supplied to GCC during the build.  If linking 
statically against libstdc++, you should also use '-static-libgcc' to 
link likewise against libgcc, or you will experience segfaults on 
program termination."

The texlive build log is full of lines like

	checking if g++-4 static flag -static works... yes

But I couldn't find the -static flag in any of the g++ command lines in 
the log.  And the following seems to indicate that libstdc++ is in fact 
being linked dynamically, unless I'm misinterpreting the results:

$ cygcheck ./pdftex.exe
D:\cygwin-1.7\tmp\tl2009\source\Work\texk\web2c\pdftex.exe
   D:\cygwin-1.7\bin\cygwin1.dll
     C:\WINDOWS\system32\ADVAPI32.DLL
       C:\WINDOWS\system32\KERNEL32.dll
         C:\WINDOWS\system32\ntdll.dll
       C:\WINDOWS\system32\RPCRT4.dll
         C:\WINDOWS\system32\Secur32.dll
   D:\cygwin-1.7\bin\cyggcc_s-1.dll
   D:\cygwin-1.7\bin\cygstdc++-6.dll

Regards,
