Bugzilla Bug 23605

Hello ... 

gcc 3.3 aborts with
 
i_rle.cc: In function `void _write_block(rle_out*)':
i_rle.cc:81: error: non-lvalue in unary `&'
make[2]: *** [i_rle.lo] Error 1


the gcc 3.3 seemed to have a prolem with the gentto patch of the 
 plotutils-2.4.1/libplot/i_rle.c file

Look on the rle_out definantion 
{
....
unsigned char oblock[256]; 
...
}


&rle->oblock[0] are pointer of char              --  gcc typeid Pc 
&rle->oblock    are pointer of an arry of chars  --  gcc  typeid PA256_c

both can be converted to  conts char * 
 
I don't know why &(const char)(rle->oblock[0]) don't compile it works on my
small testprogram
