I was inspired by this message to make clean, then rerun autoconf, then
recompile. And... now the error has moved, at least; it's in
accidental-placement.cc:
rm -f ./out/accidental-placement.dep;
DEPENDENCIES_OUTPUT="./out/accidental-placement.dep
./out/accidental-placement.o" g++ -c -Woverloaded-virtual -DHAVE_CONFIG_H
-DSTD_STRING=1 -DNDEBUG -DSTRING_UTILS_INLINED -I./include -I./out

accidental-placement.cc: In static member function `static scm_unused_struct*
Accidental_placement::calc_positioning_done(scm_unused_struct*)':
accidental-placement.cc:357: error: `isinf' undeclared (first use this
function)
accidental-placement.cc:357: error: (Each undeclared identifier is reported
only once for each function it appears in.)
make[1]: *** [out/accidental-placement.o] Error 1
make: *** [all] Error 2
This is totally baffling. From all I can tell, the chain of #include
macros does eventually end up in defining isinf (and isnan).
