Bug ID: 111756
Summary: Re-building all-gcc after source changes fails to link
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
When having modula-2 enabled in a development tree and there are any changes
that trigger rebuilds in m2/ doing a 'make all-gcc' in the build directory
will end up with
make[1]: Entering directory '/spc/abuild/rguenther/gcc13-g/gcc'

this looks like a dependency issue, maybe triggered by the change renaming
BuildInline to BuildAsm.
When I remove P3Build.[co] it seems to work. How's dependency tracking (not)
working here?
