llvm dev - Sep 2011 - [LLVMdev] cc1: error: unrecognized command line option "-Wno-overlength-strings"

Hi,

I am trying to build llvm-gcc from svn and I am getting a "cc1: error:
unrecognized command line option "-Wno-overlength-strings""
error. I have
gcc 4.1.2 and Linux 2.6.18 on 64bit. Please tell me how to fix this error.

Here is the command that caused this:

gcc -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes
-Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros
-Wno-overlength-strings -Wold-style-definition -Wmissing-format-attribute
 -DHAVE_CONFIG_H -I. -I. -I../../dst-directory/gcc
-I../../dst-directory/gcc/. -I../../dst-directory/gcc/../include
-I../../dst-directory/gcc/../libcpp/include
 -I../../dst-directory/gcc/../libdecnumber -I../libdecnumber
-I/home/asin/llvm_latest/include -I/rhel5pdi/home/asin/llvm/include
-DENABLE_LLVM -I/home/asin/llvm_latest/../llvm/include
-I/home/asin/llvm_latest/include  -D_DEBUG -D_GNU_SOURCE
-D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS   cc1-checksum.c -o
cc1-checksum.o


Thanks,
Arjun

llvm-gcc is kind of end-of-life these days (ie: you should probably be using
clang or dragonegg instead) but it looks like you're probably just using an
old version of gcc. While I haven't tried to repro your issue on gcc 4.1, it
doesn't seem to appear on  4.5[.2] (so I guess it was just a new warning
that's been added, and suppressed in the llvm-gcc build, since 4.1)

Thank you for replying. I will try to switch to clang.
