This mailing list is a place where users of GNU-win32
hang out, and so what "support" you will get is a matter of
whether we fellow users happen to know the answers to your
questions.  It is not a Cygnus support channel, and people from Cygnus
rarely participate.  If you want support from Cygnus, you need to buy
it.

Do you mean _WinMainCRTStartup?  Did you compile with
--subsystem windows?  Did the program fail when you ran it?
Please provide accurate and complete details.

Many of us are using them on Win NT, so that wouldn't seem to be the
case.

-lodbc32 means <standard library directory>/libodbc32.a, so that isn't
right.  With you own libraries, you just specify their path on the
command line.  But I think it is true that ld can't handle .LIB files.

The first "error" you mentioned is a warning that normally
still creates a .exe, so if none was created that is probably for some
other reason.
