Statistical anlysis of cygwin1.dll

[Thomas Werner-3]

hi,

i need to analyse the cygwin1.dlls assembler code for statistical
purpose. but therefor i need to know which compiler is used and its
version. every pe tool i used said "compiler unknown", so can anyone
help me?

if it's important. the file version i'm talking about is 1005.25.0.0.

please excuse my englisch and everything i did wrong (this is my first
time in a mailing list).

thank you,

thomas

If a guess that it may have been done with a gcc cross compiler of
similar version to one of those included in your version of cygwin isn't
good enough, you could rebuild it yourself.

  It is compiled by the version of gcc-4.3.4 currently shipping with the
cygwin distro.  (Usually cross-compiled from linux rather than natively, but
the same compiler version is used.)

Actually, I think it's likely that 1.5.25 was compiled with a gcc 3.4.4
cross-compiler.  4.3.4 wasn't even available when it was released.

  Oh, I missed that!  "Cygwin" has come to mean "cygwin 1.7" for me; these
days I find it increasingly hard to even remember that such a thing as 1.5
ever existed...

  Thomas, yes: CGF is undoubtedly right about the 1.5 DLL.
