[BZ #4775, BZ #4776]

2007-07-12  Jakub Jelinek  <jakub@redhat.com>
	[BZ #4775]
	* math/tgmath.h (__tgmath_real_type_sub): Formatting.
	(__tgmath_real_type): Fix if expr is const int or other const
	qualified integral type.
	(__TGMATH_UNARY_REAL_ONLY): Rewritten to avoid using statement
	expressions and handle const qualified arguments.
	(__TGMATH_BINARY_FIRST_REAL_ONLY, __TGMATH_UNARY_REAL_IMAG,
	__TGMATH_UNARY_REAL_IMAG_RET_REAL): Likewise.
	(__TGMATH_UNARY_REAL_RET_ONLY): Rewritten to avoid using
	statement expressions.
	(__TGMATH_BINARY_REAL_ONLY, __TGMATH_TERNARY_FIRST_SECOND_REAL_ONLY,
	__TGMATH_TERNARY_REAL_ONLY, __TGMATH_BINARY_REAL_IMAG): Likewise.
	(__TGMATH_UNARY_IMAG): Define.
	(conj, cproj): Use __TGMATH_UNARY_IMAG macro.
	* math/Makefile (tests): Add test-tgmath2.
	(CFLAGS-test-tgmath2.c): Add.
	* math/test-tgmath.c (fy, dy, ly, fz, dz, lz, count_cdouble,
	count_cfloat, count_cldouble): New variables.
	(NCCALLS): Define.
	(main): Check number of complex calls as well.
	(F(compile_test)): Add complex tests and tests with const qualified
	arguments.
	(y, z, ccount): Define.
	(F(cacos), F(casin), F(catan), F(ccos), F(csin), F(ctan), F(cacosh),
	F(casinh), F(catanh), F(ccosh), F(csinh), F(ctanh), F(cexp), F(clog),
	F(csqrt), F(cpow), F(cabs), F(carg), F(creal), F(cimag), F(conj),
	F(cproj)): New functions.
	* math/test-tgmath2.c: New test.

2007-07-11  Jakub Jelinek  <jakub@redhat.com>

	[BZ #4776]
	* elf/dl-load.c (_dl_rtld_di_serinfo): Output / in LD_LIBRARY_PATH,
	RPATH etc. as "/" rather than "", don't segfault on empty paths,
	instead output ".".
	* dlfcn/Makefile (distribute): Add glreflib3.c.
	(module-names): Add glreflib3.
	($(objpfx)tst-dlinfo.out): Depend on glreflib3.so rather than
	glreflib1.so.
	(LDFLAGS_glreflib3.so): New.
	* dlfcn/tst-dlinfo.c (do_test): Load glreflib3.so instead of
	glreflib1.so.
	* dlfcn/glreflib3.c: New file.

	* intl/finddomain.c (_nl_find_domain): If _nl_explode_name
	returned -1, return NULL.
	* intl/explodename.c (_nl_explode_name): Return -1 if
	_nl_normalize_codeset failed.
