Compiling GSL on IRIX 6.5 with gcc

["Mr. Roman Putanowicz" <romek at carme dot sect dot mce dot hw dot ac dot uk>]

Hi, 
These kind of errors were already reported by Craig P Prescott (4 Oct 2000) 
(http://sources.redhat.com/ml/gsl-discuss/2000/msg00557.html)
but I just write to confirm that they still are there.

I used GSL-1.0 on IRIX 6.5, gcc version 2.95.3 with compiler
flags: -g -O2

It compiles but make check crashes in block/:

Program received signal SIGSEGV, Segmentation fault.
0x1000c3a4 in gsl_block_complex_long_double_fscanf (stream=0xfb525d8, 
    b=0x100300ce) at fprintf_source.c:85
85                data [MULTIPLICITY * i + k] = tmp;

After recompiling with -O0 make check reports no errors !
It seems that after gcc 2.7 turning optimization on may sometimes break a code.

Anyway, not optimized code works well.

There was also one more problem already mentioned  on the list
(http://sources.redhat.com/ml/gsl-discuss/2001/msg00157.html) :
I had to increase (as a root) argument buffer to 40960:
   systune ncargs 40960
in order to make libtool work.

Regards

Romek
