Hi all,

I am attempting to build a modified cygwin[x].dll in order to incorporate some 
changes to the retained Windows ACLs (Access Control Lists), for which a 
replacement winsup/cygwin/sec_acl.cc has been written by Srinivasa Battula.

I normally do cross-compilation from Linux to Win32 but in this case it 
appears to be much(!) easier to install Cygwin on Win XP and do ./configure; 
make etc there, however ...

The build fails for the current Cygwin install and the source snapshot from 
2006-08-10 with an error report as follows (approx):

configure: configuring in libc
configure: running /bin/sh ' ... /newlib/libc/configure' .....
.....
configure: error 'CFLAGS' has changed since the previous run:
configure: former value  -O2 -g -O2
configure: current value: -O2 -g -O2

This is without any 'previous run' !

Has anyone any ideas, seeing as the download page for snapshots asserts that 
snapshots are only released for download if they successfully build ?
