On Intrepid, a BG/P system up at Argonne with some fun old IBM XL compilers, a user of mine is seeing gnulib/float.h containing the line #include " " which appears to be arising from configure:13477: checking absolute name of <float.h> configure:13516: result: "" due to http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob_plain;f=m4/float_h.m4 where host_cpu='powerpc64' host_os='linux-gnu' host_vendor='unknown'
What information might I collect to help debug this? This is atop gnulib HEAD. I have a full config.log sitting around and would be happy to send it someone's way in addition to the generated configure file. - Rhys
