Sprinkle <sys/featuretest.h> where _*_SOURCE macros are consulted.

Otherwise, the feature tests might come out wrong.  For example,
header files that check for _NETBSD_SOURCE won't get the default when
no other _*_SOURCE macros are defined; header files that check for
_POSIX_C_SOURCE might miss _XOPEN_SOURCE, which is supposed to imply
a corresponding _POSIX_C_SOURCE.

PR lib/58752: various header files test _*_SOURCE macros but don't
include sys/featuretest.h

Some stupid pkgsrc stuff insists on -std=c89, duh!
Use __inline instead of inline.

Rebase to HEAD as of a few days ago.

sync with head

Change __isinf and __isnan from macros to inline functions. The macros do
collide with newer gcc libstdc++.

merge to -current.

Define __INFINITY as huge_val since VAX FP doesn't have infinities.

merge ktrace-lwp.

Fix the sync with head I botched.

* Turn isinf(3) and isnan(3) into C99-style macros.
* Make it possible for ports to override these (i.e., VAX).
* Remove isnanl(), which was internal to libc only.

Move FP_ROP and FP_DIRTYZERO from <math.h> to <vax/math.h> (where they
would have ended up if I hadn't missed the latter file in the commit).

C99 7.12#4: provide INFINITY, which defaults to HUGE_VALF.
If infinities are not available, the machine-dependent header must define
__INFINITY as a positive constant of type float that overflows.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

file math.h was added on branch thorpej_scsipi on 2000-11-20 20:32:56 +0000

C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.
