Bug ID: 89140
Summary: libiberty/pex-unix.c fails to compile in
aarch64-to-x86_64 cross build
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org

patch to correct pex-unix.c header file inclusion
In an aarch64-to-x86_64 cross-GCC build scenario, the libiberty configuration
process determines that getrusage is not available but wait4 is. This leads to
a situation where resource.h is not included, but there is a declaration of
type struct rusage.
I was able to get the compile to succeed without issues just by changing the
condition under which resource.h is included, see attached patch.
