[MINC-development] libminc build failures on mipsel

[Steve M. Robbins]

Hi,

Bert -- your recent changes to develop fixes the build problem I reported 
recently.  Thanks!

Now the develop branch builds on all Debian architectures -- except the Little 
Endian MIPS (mipsel and mips64el).  These both fail the tests minc_types-1 and 
minc_types-2.

    See: https://buildd.debian.org/status/package.php?p=libminc

Note that the big-endian MIPS (architecture "mips") passes the test.  


The output is below.  It seems (is the diff backwards?) that instead of 
mapping  -2 * FLT_MAX to the lowest value of the integral range it turns out 
to be the largest value.  

I haven't traced further, yet.

-Steve
