There is some advance.

I put the stlport libraries in /lib.

$ g++ -c -o foo.o foo.cpp

$ g++ -o foo_port.exe foo.o -lstlport

$ g++ -o foo_orig.exe foo.o

$ wc foo*.exe
    462    5847  478971 foo_orig.exe
    462    5847  478971 foo_port.exe
    924   11694  957942 total

$ cygcheck foo*.exe
Found: .\foo_orig.exe
foo_orig.exe
  C:\cygwin\bin\cygwin1.dll
    C:\WINNT\System32\KERNEL32.dll
      C:\WINNT\System32\NTDLL.DLL

Found: .\foo_port.exe
foo_port.exe
  C:\cygwin\bin\cygwin1.dll
    C:\WINNT\System32\KERNEL32.dll
      C:\WINNT\System32\NTDLL.DLL


So, neither wc nor cygcheck see any difference between foo_orig.exe and foo_port.exe.

However,
$ cmp -b foo*.exe
foo_orig.exe foo_port.exe differ: byte 137, line 2 is 167 w 146 f

$ cmp -l foo*.exe
   137 167 146
   217  52  31


Is foo_port.exe really STLported?


Appendix. Extra info.
$ g++ -v -o foo_orig foo.o
