Hi bug-guile! Recent glibc-2.34 released changed attribute macros slightly which broke older gnulib macros. Fixed in gnulib upstream as: https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=0c907f7da13232908f05c415b8cec56024071906
guile.git now fails to build on x86_64-linux as: ``` CC regex.lo In file included from regexec.c:1368, from regex.c:74: ./malloc/dynarray-skeleton.c:195:24: error: expected declaration specifiers or '...' before '(' token 195 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:205:51: error: expected declaration specifiers or '...' before '(' token 205 | __attribute_maybe_unused__ __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:216:24: error: expected declaration specifiers or '...' before '(' token 216 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:225:24: error: expected declaration specifiers or '...' before '(' token 225 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:239:24: error: expected declaration specifiers or '...' before '(' token 239 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:248:24: error: expected declaration specifiers or '...' before '(' token 248 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:260:24: error: expected declaration specifiers or '...' before '(' token 260 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c:270:24: error: expected declaration specifiers or '...' before '(' token 270 | __attribute_nonnull__ ((1)) | ^ ./malloc/dynarray-skeleton.c: In func ``` Would it be reasonable to sync gnulib and cut a guile point release compatible with it?
