Subject:	[Bug: gcc-3.2-1] Cygwin DLL (CVS HEAD) build failure - gcc uses wrong include path order.
Date:	Thu, 24 Oct 2002 17:27:00 +0100

I tried to build the Cygwin DLL from CVS, but ran into an error caused by
gcc inserting an unasked for "-isystem
/usr/lib/gcc-lib/i686-pc-cygwin/3.2/../../../../include/w32api" into the
cpp0.exe command line. That path contracts to /usr/include/w32api - so gcc
uses the installed w32api, not the w32api in the source tree. And, tty.cc is
using GetConsoleWindow, which hasn't yet appeared in the latest released
w32api, so it is essential that the one from the source tree be used
instead.

This seems to be a bug in gcc-3.2-1. gcc2-2.95.3-10 gets further on in the
compile before hitting an undefined reference to dcgettext__ whilst making
dumper.exe, which has already been mentioned and diagnosed on list.

Max.
