Bug #114373 for Perl-Dist-Strawberry: 5.22.2.1: (cosmetic) problems with Makefile's generated for modules

First of all, a lot of thanks for releasing this distribution! (These bugs were detected while creating Math::Pari v2.01080900. Since it looks like Strawberry uses its own build of dmake, these warnings become the bugs in Strawberry perl. ;—[ ) ========================== (A) Enabling tracing in dmake exposes the following warnings: dmake: K:\get\strawberry-perl-5.22.2.1-32bit-PDL\c\bin\startup\config.mk: line 3: Warning: -- Macro `OS' redefined after use dmake: K:\get\strawberry-perl-5.22.2.1-32bit-PDL\c\bin\startup\startup.mk: line 143: Warning: -- More than one prerequisite for %-target. Use :| ruleop or indirect prerequisites. dmake: K:\get\strawberry-perl-5.22.2.1-32bit-PDL\c\bin\startup\startup.mk: line 147: Warning: -- More than one prerequisite for %-target. Use :| ruleop or indirect prerequisites. dmake: makefile: line 329: Warning: -- The .SUFFIXES target has no special meaning and is deprecated. Note that Makefile.PL does not mention the .SUFFIXES rule; this rule is fully autogenerated. ========================== (B) The module has a child Makefile.PL in a subdirectory, which builds a C library. The toplevel Makefile.PL uses the standard practice of having a rule (which, essentially, “inherits” dependencies of the child makefile): $(MYEXTLIB): libPARI/Makefile FORCE cd libPARI && $(MAKE) $(PASTHRU) However, this causes a warning from dmake: dmake: Warning: -- Target [libPARI\libPARI.a] was made but the time stamp has not been updated. ========================== (C) I have no idea for the reason for this warning: dmake: Warning: -- Found file corresponding to virtual target [libPARI\pariinl.h]. The file exists indeed, but what makes it virtual is not clear. The lines of tracing related to this file are: Checking prerequisite [libPARI\pariinl.h] dmake: Infering prerequisite(s) and recipe for [libPARI\pariinl.h] dmake: Trying prerequisite [libPARI\RCS\pariinl.h] for [libPARI\pariinl.h] dmake: Time stamp of [libPARI\pariinl.h] is 1401650795 dmake: >>>> Making [libPARI\pariinl.h] dmake: Updating [libPARI\pariinl.h], (1462579885 > 1401650795) dmake: <<<< Set [libPARI\pariinl.h] time stamp to 1462579885 dmake: Warning: -- Found file corresponding to virtual target [libPARI\pariinl.h]. Below I attach the context of these lines (if needed).
