* When boot loader support is compiled w/ UFS and HAMMER together, which
  is the default (note: HAMMER booting's never worked well)... the probe
  order was to check for the hammer volume header first and UFS second.

* Change the probe order to check for UFS first and HAMMER second.  The
  reason is that a 'newfs' (for UFS) doesn't wipe the hammer volume header
  because the ufs's newfs tries to 'skip' the partition reserved area of
  the disk.

  This is a huge throwback to the original BSD fdisk/disklabel which put
  the boot code INSIDE the 'a' partition.

* The DragonFly disklabel64 (which is now the default) does not have this
  problem so we could probably at some point adjust the UFS 'newfs' code to

23 months agoncurses: Fix pkgsrc check and use of ncurses
John Marino [Tue, 7 Aug 2012 11:35:26 +0000 (13:35 +0200)]
ncurses: Fix pkgsrc check and use of ncurses

Without the macro SET_NEED_WCHAR_H defined, the ncurses header will not
include wchar.h which is where the wint_t type is defined.  This breaks
any program loading ncurses.h without defining this macro because several
functions use the wint_t type.

Define wint_t as int if wchar.h isn't included.  This fixes the ncurses
check on several pkgsrc configuration checks and allows the package to
build with the system ncurses.

here (which is to completely override the /usr/include path).

I didn't verify in 100% detail, but all evidence looks like the reason is
that when -I is present on the command line, the paths of the headers
which are included by headers from this directory are not prefixed with
-isysroot's argument.

So for now, use -iprefix and -iwithbeforeprefix for /usr/include, which
seem to do what we want.
