$NetBSD: manual-libtool.m4,v 1.26 2009/07/08 21:01:43 markd Exp $

Local pkgsrc changes:
- override the basename to point to the actual backend compiler,
  critical e.g. on Solaris
- portability fixes for print on Interix
- override for shlib naming policy on various platforms
- QNX support
- Interix3 support
- disable static linkage on OS X by default
- DragonFly support decoupled from FreeBSD
- support g95 on NetBSD
