AIX aix 3 4 00FFFFFF4C00 (AIX 4.3.3)
>Description:
When I tried to build gnu sed on AIX 4.3.3, the configure script detects _LARGE_FILES=1 and _LARGE_FILE_API=1 had to be set to use large files.

stdio.h installed by gcc-3.2.2 into /usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include checks both defines separately and declares both functions groups which are using fpos_t/fpos64_t: fgetpos and fgetpos64 in a manner which causes gcc invoked with
/usr/local/bin/gcc -DHAVE_CONFIG_H -I. -I. -I.. \
-I../lib -I../intl -I.. \
-DLOCALEDIR=\"/usr/local/share/locale\" \
-g -pipe -O2 -mcpu=603e -MT fmt.o -MD -MP -MF \
".deps/fmt.Tpo" -c -o regex.o \
`test -f 'regex.c' || echo './'`regex.c

to fail with:
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:448: conflicting types for `fgetpos64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:288: previous declaration of `fgetpos64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:451: conflicting types for `fseeko64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:394: previous declaration of `fseeko64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:452: conflicting types for `fsetpos64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:290: previous declaration of `fsetpos64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:453: conflicting types for `ftello64'
/usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.2.2/include/stdio.h:395: previous declaration of `ftello64'

I created a patch which corrects the issue, but maybe not the problem, because I don't know why the author wants both _LARGE_FILES and _LARGE_FILE_API existing in concurrent manner.
