Porting notes
This section describes common build breakages, example fixes and a bit of explanation. Useful to craft the patch and explain upstream why change is needed.

binutils-2.31.1

 * Test failures

binutils-2.32

 * This release of binutils fixes a bug regarding section alignment in debug information. As a consequence, you need >=dev-libs/elfutils-0.175 and >=sys-devel/gdb-8.3 for proper operation. If you do not use the abovementioned minimum versions, typical symptoms include failure to decode debug information and failure to complete a linux kernel build.

gcc-8

 * error: -Wabi won't warn about anything [-Werror=abi], example

gcc-9

 * error: expected '(' before 'volatile', example

glibc-2.26

 * sysmacros.h: missing major, minor macros
 * xlocale.h not found
 * glibc-2.26+ /etc/nsswitch.conf changes
 * Migrating from SunRPC to libtirpc

glibc-2.27

 * pow10, pow10f and pow10l removed
 * ld: cannot find -lieee

glibc-2.28
Tracker:


 * fseeko, fflush are broken for bundled gnulib, example
 * linknamespace tests (>400) fail when upgrading from 2.27, example
 * error: FILE {aka struct _IO_FILE } has no member named ..., example
 * Test failures

libffi-3.3
Tracker:


 * FFI_SYSV was not declared in this scope, example
