I see that /opt/developerstudio12.6/bin/cc on that machine is Oracle Studio 12.6 
Sun C 5.15 patched to 152881-04 2019/03/08, whereas my copy (the free one) is 
the unpatched Oracle Studio 12.6 Sun C 5.15 2017/05/30. I did try the latest 
Autoconf with my free copy, and it reported a single unexpected failure:

330: AC_FC_LINE_LENGTH                               FAILED (fortran.at:1055)

This problem is that whereas the older Sun Fortran 95 8.3 Patch 127000-13 
2010/01/26 (which I used earlier) does not support lines longer than 132 
columns, the newer Oracle Studio 12.6 Fortran 95 8.8 2017/05/30 (which I just 
now used) supports lines as long as 250 columns. Unfortunately the 
Autoconf-generated 'configure' uses a test program with a line of 138 (which 
succeeds on the newer Oracle Studio 12.6), and 'configure' then concludes that 
the line lengths are "unlimited" (i.e., as long as 254 columns), so the test 
suite eventually tests a line with 253 columns and that test fails.

I installed the attached patch to fix this test glitch. The basic idea is to 
test 250 columns not 253, and to document the limit as 250 not 254.
