In particular, I get "error: 'SSP_blobP' was not declared in this scope" in negotiate_sspi_auth.cc. The only place I've found where SSP_blobP type is defined is sspwin32.h, and it is defined only if _SQUID_WINDOWS_ macro is also defined:

There are places in Squid code which are processed only when both _SQUID_CYGWIN_ and _SQUID_WINDOWS_ are defined, so as an experiment I've tried patching osdetect.h to make _SQUID_WINDOWS_ also defined when compiling on Cygwin, but that immediately produced hell of new errors during make: unresolved references, conflicting function declarations, etc.

It is correct. CygWin presents a POSIX API for code and builds the same
as what a Unix/LinuxBSD build does.

The SSPI helpers are only for Native Windows API builds done with Visual
Studio and maybe MinGW. Neither of which are working yet.


PS. Windows packages are available from Diladele if you just want the
latest version.
