Subject: [PATCH] Adapt Configure to GCC version 10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
Please note I did not test it because I don't have GCC 10 available.
