--- Comment #2 from Richard PALO <richard at netbsd dot org> --- I can't seem to recreate this now, although I'm not that sure it had to do with an issue involving the compiler on illumos where the native libm 'complex.h' was being erroneously fixed up causing precompiler problems with missing closing brace. https://www.illumos.org/issues/5367 updated as well was fixincludes for 4.9.2 with: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52168 and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61649 if I come across this issue again I'll post back.
