commit 4e6c98f3df065743e5598c158d71af7fc8f63a25
Author: G. Branden Robinson <[email protected]>
AuthorDate: Thu Apr 9 00:59:58 2026 -0500
[build]: Drop obsolescent configuration code.
Drop no longer needed check for `struct exception`. It was used only by
the now-deleted "src/libs/libgroff/matherr.c".
* m4/groff.m4 (GROFF_STRUCT_EXCEPTION): Delete.
* configure.ac: Drop interpolation of `GROFF_STRUCT_EXCEPTION`.
* Makefile.am: Stop advertising availability of `HAVE_STRUCT_EXCEPTION`
preprocessor symbol.
