Log Message:
-----------
Adapt Configure to GCC version 10
I got a notice from Jeff Law <[email protected]>:
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 do not have GCC 10 available, I tested it by faking the version
with:
--- a/Configure
+++ b/Configure
