- Subject: [PATCH] Adapt Configure to GCC version 10
-
- I got a notice from Jeff Law <law@redhat.com>:
-
- Your particular package fails its testsuite. This was ultimately
- tracked down to a Configure problem. The perl configure script treated
- gcc-10 as gcc-1 and turned on -fpcc-struct-return. This is an ABI
- changing flag and caused Perl to not be able to interact properly with
- the dbm libraries on the system leading to a segfault.
-
- His proposed patch corrected only this one instance of the version
- mismatch. Reading the Configure script revealed more issues. This
- patch fixes all of them I found.
