bootstrap currently fails for mainline on AIX, first because of problems like
...trunk/libcpp/system.h:47:0: error: "fopen" redefined [-Werror]
.../include-fixed/stdio.h:110:0: note: this is the location of the previous
definition
Indeed, libcpp/system and gcc/system.h have
/* Use the unlocked open routines from libiberty. */
...
#define fopen(PATH,MODE) fopen_unlocked(PATH,MODE)
#define fdopen(FILDES,MODE) fdopen_unlocked(FILDES,MODE)
#define freopen(PATH,MODE,STREAM) freopen_unlocked(PATH,MODE,STREAM)
while /usr/include/stdio.h on AIX (5.3 at least) has
#ifdef _LARGE_FILES
...
#define fopen fopen64
#define freopen freopen64
gcc/system.h already has some provision for this sort of mishap:
#ifdef fopen /* fopen is a #define on VMS. */
#undef fopen
#endif
The attached patch is a suggestion to simplify and widen this a bit
to catch all the AIX related problems to date.
Tested by checking that bootstrap proceeds (and ends successfully
after another change, to be posted shortly) on powerpc-ibm-aix5.3.0
with languages=all,ada. Also bootstrapped on i686-suse-linux.
OK ?
Thanks in advance,
Regards,
Olivier
