System: NetBSD osprey.buzzard.freeserve.co.uk 1.6U NetBSD 1.6U (OSPREY) #89: Wed Jun 25 22:06:37 BST 2003 rearnsha@osprey.buzzard.freeserve.co.uk:/work/build/src/sys/arch/cats/compile/OSPREY cats
Architecture: arm
Machine: cats
>Description:
	The flex package is disabled for NetBSD because flex is included in
	the base system.  However, flex can generate lexers that are C++
	classes (option -+), and when it does the code generated:
	1) Includes a header that isn't visibile in the gcc-3 package search
	path (Flexlexer.h is in /usr/include/g++, which is specific to our
	in-tree compiler)
	2) Doesn't compile even if copied somewhere where that gcc-3 will 
	search.

	There are one or two simple patches to the include file and another
	to the skeleton files that would make the code gcc-3 clean.
	
>How-To-Repeat:
	Try to build devel/umbrello on a machine that's using gcc-3 for
	building packages.
	
>Fix:
	
	The main problem is that in gcc-3 istream is no-longer a class, so
	the flex skeleton file is in error to declare it that way instead of
	pulling in <iostream>.  There may be other namespace problems, but I'm
	not enough of a c++ programmer to be sure.
