If the newlib .info files are installed using install-info, 'info libc' and
'info libm' don't work.
This seems to be due to the formatting of the directory entry line not being
quite right, so fix that.
Also use @direntry texinfo command, rather than writing .info directory entry
literally.
Also use @dircategory texinfo command to place into 'Newlib' category, rather
than ending up in 'Miscellaneous'

* libm/libm.texinfo: Ditto.
Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk>

warning.
* libm/math/ef_pow.c (__ieee754_powf): Ditto.

* libm/math/e_rem_pio2.c (__ieee754_rem_pio2): Ditto for variable z.
* libm/common/sf_round.c (roundf): Remove signbit variable since result
is never used.
* libm/common/s_log2.c: Change from using M_LOG2_E to M_LN2 define
(from math.h--the latter is POSIX, the former non-standard).
* libm/common/sf_log2.c: Ditto. Change cast for M_LN2 from float to
float_t (in case all math not done in float).
* libc/include/math.h: Ditto (same 2 things as sf_log2.c).
* libm/common/s_lrint.c (lrint): Annotate shift operations with
possible shift amount ranges, and use SAFE_RIGHT_SHIFT to avoid
undefined behaviour.
* libm/common/s_llrint.c (llrint): Likewise.
* libm/common/s_lround.c (lround): Correct some comments on ranges.
* libm/common/s_llround.c (llround): Likewise.
(SAFE_RIGHT_SHIFT): Likewise.
* libm/common/s_llround.c (llround): Annotate shift operations with
possible shift amount ranges, and use SAFE_RIGHT_SHIFT to avoid
undefined behaviour.
* libm/common/s_lround.c (lround): Likewise.
* libm/common/s_rint.c: Fix error when integral part had 18 bits and
fraction had bits set beyond first radix bit. Also, make 2-part
adjustment consistent with 1-part adjustment when adjusting fractional
bits.
* libm/common/sf_rint.c: Make fractional-bit adjustment consistent
with s_rint.c by setting 0b.01 instead of 0b.001.
* libc/stdlib/getenv.c: Delete "char *_findenv_r ();", as is not a
proper prototype, and is properly prototyped in stdlib.h, anyway.
* libc/stdlib/getenv_r.c: Ditto.
* libc/search/hash.c: Add _DEFUN to __hash_open() declaration; add
#define __DBINTERFACE_PRIVATE to activate prototypes from db_local.h.
* libc/search/db_local.h: Correct __hash_open() prototype.
* libc/sys/linux/cmath/math_private.h: Eliminate compiler warnings:
Remove #define INFINITY (redefines from math.h); remove #define __isnanf
and #define __isinff isinff.
* libm/common/s_ilogb.c: Adjust documentation to reflect new returns
(see next items) and that ilogb() and ilogbf() are C99/POSIX.
* libm/common/s_ilogb.c (ilogb): Use C99/POSIX FP_ILOGB0 and
FP_ILOGBNAN returns for 0 and NAN arguments, respectively, instead of
the prior -INT_MAX and INT_MAX. The FP_ILOGBx defines in math.h
presently match the prior hard-codes, so no functional change is
actually introduced. (Not at this time, nor planned, but the values
are permitted to be different, so subsequent edits of math.h could
possibly cause a functional change.)
* libm/common/sf_ilogb.c (ilogbf): Ditto.
* configure.in: Add configuration test for long double type existing
and set flag _HAVE_LONG_DOUBLE if true. Fix INIT_ARRAY (.init_array)
and _LDBL_EQ_DBL tests to not link so that will work with
cross-compilers.
* configure: Regenerated.
* Makefile.in: Ditto.
* newlib.hin: Add _HAVE_LONG_DOUBLE flag.
* libc/include/math.h: Change non-builtin defines for HUGE_VAL,
HUGE_VALF, and HUGE_VALL to be constant expressions. Add definitions
for the non-builtin case for INFINITY and NAN. Gate HUGE_VALL and
union __ldmath definitions with (new) _HAVE_LONG_DOUBLE.
*libm/common/s_infconst.c: Change definitions to use values from
float.h instead of non-so-portable integer forms. Mark as being
deprecated (because now removed from math.h, are not used anywhere
in Newlib, itself).
