I have posted the other part (i.e. changes to the gettext version) on the bug-gettext mailing list, but it is not showing up in the archives yet. The changes in this sync up are: - Bunch of macro jugglery does not affect glibc - Definition of PRI_MACROS_BROKEN that fixes its Wundef warning - Open domain_file in binary mode - Avoid use of the GNU-specific TEMP_FAILURE_RETRY. This was a deliberate change in glibc, but I thought reverting it here would be a good idea to keep these sources free of GNU extensions. - Cast alloca return to build with C++ compilers I have done a build and check run on x86_64 to verify that this does not break anything. I will follow up with the gettext folks on their end of the changes. Siddhesh Sync up with gettext. * intl/loadmsgcat.c: Define O_BINARY if not defined. [_MSC_VER]: Include malloc.h [_LIBC]: Define PRI_MACROS_BROKEN if it is not defined. (get_sysdep_segment_value) [!__UCLIBC__]: Return "I" flag. (_nl_load_domain): Open DOMAIN_FILE in binary mode. Don't use TEMP_FAILURE_RETRY. Cast return of alloca. [!_LIBC] Call gl_rwlock_init. [IN_LIBGLOCALE]: Call _nl_find_msg with one less argument. diff --git a/intl/loadmsgcat.c b/intl/loadmsgcat.c index 7497172..cce55b6 100644 --- a/intl/loadmsgcat.c +++ b/intl/loadmsgcat.c @@ -39,14 +39,19 @@ # define alloca __builtin_alloca # define HAVE_ALLOCA 1 #else -# if defined HAVE_ALLOCA_H || defined _LIBC -# include +# ifdef _MSC_VER +# include +# define alloca _alloca # else -# ifdef _AIX - #pragma alloca +# if defined HAVE_ALLOCA_H || defined _LIBC +# include # else -# ifndef alloca +# ifdef _AIX + #pragma alloca +# else +# ifndef alloca char *alloca (); +# endif # endif # endif # endif @@ -88,7 +93,19 @@ char *alloca (); #ifdef _LIBC # include "../locale/localeinfo.h" # include +#endif + +/* Handle multi-threaded applications. */ +#ifdef _LIBC # include +#else +# include "lock.h" +#endif + +#ifdef _LIBC +# ifndef PRI_MACROS_BROKEN +# define PRI_MACROS_BROKEN 0 +# endif #endif /* Provide fallback values for macros that ought to be defined in . @@ -472,6 +489,24 @@ char *alloca (); # define freea(p) free (p) #endif +/* For systems that distinguish between text and binary I/O. + O_BINARY is usually declared in . */ +#if !defined O_BINARY && defined _O_BINARY + /* For MSC-compatible compilers. */ +# define O_BINARY _O_BINARY +# define O_TEXT _O_TEXT +#endif +#ifdef __BEOS__ + /* BeOS 5 has O_BINARY and O_TEXT, but they have no effect. */ +# undef O_BINARY +# undef O_TEXT +#endif +/* On reasonable systems, binary I/O is the default. */ +#ifndef O_BINARY +# define O_BINARY 0 +#endif + + /* We need a sign, whether a new catalog was loaded, which can be associated with all translations.
