Thanks for pointing this out. I've applied this patch to fix this by adding a newline at the end of the test input (which is what I did for all the cases where adding AC_LANG_SOURCE resulted in autoconf errors if the last line of the AC_LANG_SOURCE argument contained '#'; I don't know how related the issues are, but it's at least less cryptic for the reader than using a quadrigraph). Avoid stray [] in ia64 assembler test. Noted in <https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00034.html>. Fix by adding extra newline in test input is analogous to many such newlines added in cases where argument to a newly added AC_LANG_SOURCE had a preprocessor directive on its last line. 2018-11-01 Joseph Myers <jos...@codesourcery.com> * configure.ac (gcc_cv_as_ia64_ltoffx_ldxmov_relocs): Add newline at end of assembler input text. * configure: Regenerate.
