I've hit a build problem when upgrading from 4.7.0 to 4.7.1. I'm using
the same build recipe[1], so it's most probably a change in GCC code.
The immediate error I'm hitting is this:
rm -f rts/libgna*.so
cd rts; `echo "/home/raos/mgar/gcc4/trunk/work/solaris10-sparc/build-isa-sparcv8plus/objdir/./gcc/xgcc

>From asking around so far, it's similar to this minimal example:
static int c = 1;
int f(int a) {
return a+c;
}
gcc -shared -o liba.so liba.c

c 0x4 /var/tmp//ccqHaWcX.o

collect2: ld returned 1 exit status
In this case, the fix is to add -fpic to the invocation. But in the
build logs I do see -fPIC, and it still fails, so I'm not sure if it's
really the same kind of problem.
Has anyone else encountered this error?
