Hi,

I am now trying to run Debian on Renesas SH(sh4) CPU.
  http://buildd.debian-ports.org/status/architecture.php?suite=unstable&a=sh4

libvigraimpex FTBFS on sh4.
  http://buildd.debian-ports.org/status/fetch.php?pkg=libvigraimpex&arch=sh4&ver=1.7.1%2Bdfsg1-1&stamp=1310539375

Because ftbfs by NaN check, -mieee option of gcc is necessary to build
libvigraimpex om sh4

I created a patch which revised this problem.
Could you apply this patch?

Note:  libvigraimpex is FTBFS by other problems even if you apply this patch.
Make which, and this patch is necessary.

Best regards,
 Nobuhiro
