+ log1p: Provide replacement for Minix and MSVC.
+ * lib/math.in.h (log1p): New declaration.
+ * lib/log1p.c: New file.
+ * m4/log1p.m4: New file.
+ * m4/math_h.m4 (gl_MATH_H): Test whether log1p is declared.
+ (gl_MATH_H_DEFAULTS): Initialize GNULIB_LOG1P, HAVE_LOG1P.
+ * modules/math (Makefile.am): Substitute GNULIB_LOG1P, HAVE_LOG1P.
+ * modules/log1p (Files): Add lib/log1p.c, m4/log1p.m4.
+ (Depends-on): Add math, isnand, log, round.
+ (configure.ac): Invoke gl_FUNC_LOG1P. Arrange to compile replacement if
+ HAVE_LOG1P is 0.
+ * tests/test-math-c++.cc: Check the declaration of log1p.
+ * doc/posix-functions/log1p.texi: Mention the replacement.

+
+ math tests: Small simplification.
+ * tests/test-exp.h (test_function): Use the same err_bound for
+ 'double' on platforms with sizeof (long double) == sizeof (double)
+ than on platforms with sizeof (long double) > sizeof (double).
+ * tests/test-exp2.h (test_function): Likewise.
+ * tests/test-expm1.h (test_function): Likewise.
+ * tests/test-log.h (test_function): Likewise.

+ Fix some comments.
+ * lib/expl.c: Fix an ambiguous comment.
+ * lib/expm1.c: Likewise.
+ * lib/expm1l.c: Likewise.
+ * lib/exp2.c: Likewise.
+ * lib/exp2l.c: Likewise.

+
+ regex: allow inclusion of <regex.h> before <limits.h>
+ Without this patch, portable programs had to include <limits.h> before
+ <regex.h> if they wanted a consistent value for RE_DUP_MAX.
+ I ran into this problem with a test version of GNU grep on Solaris 8.
+ * lib/regex.h: Include <limits.h> if _REGEX_INCLUDE_LIMITS_H.
+ This is done conditionally so that this change can be merged
+ back to glibc.
+ * m4/regex.m4 (gl_REGEX): Define _REGEX_INCLUDE_LIMITS_H if
+ using the included regex.
+
+ fts: depend on fdopendir
+ * modules/fts (Depends-on): Depend on fdopendir. This is needed
+ on Solaris 8, at least, since it lacks fdopendir. Evidently the
+ problem was introduced when fdopendir was split out.

+
+ Remove unused variables.
+ * m4/fmodf.m4 (gl_FUNC_FMODF): Remove unused variable 'i'.
+ * m4/remainderf.m4 (gl_FUNC_REMAINDERF): Likewise.

+
+ isnanf-nolibm: Fix last commit.
+ * lib/isnanf-nolibm.h [IRIX]: Don't include <ieeefp.h>. Declare isnanf.
+
isnanf-nolibm: Make it work on IRIX 6.5 with cc.
* lib/isnanf-nolibm.h [IRIX]: Include <ieeefp.h>.
