[Tru64 UNIX V4.0F/V5.1] libobjc/sendmsg.c patch


Bootstrapping gcc 3.0 20010221 (prerelease) failed on Tru64 UNIX V4.0F or
V5.1 when building libobjc:

/tmp/gcc/gcc/xgcc -B/tmp/gcc/gcc/ -B/vol/gcc/share/alpha-dec-osf4.0f/bin/ -B/vol/gcc/share/alpha-dec-osf4.0f/lib/ -isystem /vol/gcc/share/alpha-dec-osf4.0f/include -c -I. -I/vol/gnu/src/gcc/gcc-3.0-branch/libobjc -g -mieee -DIN_GCC -DIN_TARGET_LIBS -I/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/objc -I/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/../gcc -I/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/../gcc/config -I../../gcc -I/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/../include /vol/gnu/src/gcc/gcc-3.0-branch/libobjc/sendmsg.c   -DPIC -o .libs/sendmsg.o
/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/sendmsg.c: In function `__objc_forward':
/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/sendmsg.c:600: conflicting types for `strlen'
/vol/gnu/src/gcc/gcc-3.0-branch/libobjc/sendmsg.c:600: warning: extern declaration of `strlen' doesn't match global one

This happens because either the original <standards.h> or the fixinclude'd
one define _NO_PROTO and _NONSTD_TYPES iff __GNUC__ && !__STDC__
(!__STRICT_ANSI__ after fixincludes) are defined: this way, an unprototyped
declaration of strlen() is used:

extern unsigned int strlen();

instead of

extern size_t   strlen __((const char *));

Since strlen() is used without explicit prototype in many other C sources
in libobjc, I just deleted it to avoid this conflict.
