Unable to build MinGW OpenLDAP in Cygwin: gcc no longer supports the "-mno-cygwin" flag?

Hi, OpenLDAP developers,

I am trying to build OpenLDAP client libraries on Windows by following the instructions listed on the OpenLDAP.org Faq-O-Matic.

Building MinGW OpenLDAP in a Cygwin Environment http://www.openldap.org/faq/data/cache/302.html

In the MinGW Support in Cygwin section http://www.openldap.org/faq/data/cache/301.html

To create the wrapper script, start the Cygwin bash shell, and execute the following: $ cd /usr/bin $ cat > mgcc #!/bin/sh gcc -mno-cygwin $* ^D

The problem is that it seems gcc no longer supports the "-mno-cygwin" flag:

$ gcc -mno-cygwin gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler.

I am currently using Cygwin version ...

$ uname -a CYGWIN_NT-6.1-WOW64 hostname 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin

And my gcc version is ...

$ gcc -v Using built-in specs.

Any help would be much appreciated.

Thanks.
