> Sorry, I've missed ext/configsub.rb and fixed now.
Thank you very much for the quick fix ... however there an old build
problem (under VS6 and VS7) still remains The culprit is
mswin32-ruby17.def (generated by mkexport.rb).
The offending lines look like
---
....
SafeFree
Win32System
_real@0000000000000000
_real@3eb0c6f7a0b5ed8d
....
_real@bff0000000000000
_real@c1d0000000000000
chown
closedir
....
----
Without removing _real@0000000000000000 ... (this must be done during
the build process) the build fails with a link error complaining about missing
symbols. Additionally it is probably save to remove all non human readable
symbols from the export list in mswin32-ruby.def. Besides shrinking
mswin*.dll in size it also has a measurable performance effect
( ~ 10-15 % in the test script below).
Using a full /Ox optimization (this includes a frame-pointer optimization)
removes all of the non-readable symbols from the export list and adds
another ~ 10 - 15 % speed improvement in my test script below.
Unfortunately running ``nmake test'' (or installing) uncovers a problem with
printf - for example
---
ruby -e 'printf "bla %d bla %s\n", 2,Object'
---
-e:1:in `printf': failed to convert Class into Integer (TypeError)
from -e:1
---
Given the not insignificant performance increase it might be a good idea
to further investigate this issue. At a first glance I did not find any other
problem associated to the usage of a full /Ox optimization - for example
``nmake test'' succeeds after modifying the ``printf'' lines of the
``sample/test.rb'' file in Ruby;s cvs-source tree.
The biggest performance booster is a switch of compliers: Using the
VS7-C++ compiler over a VS6-C++ compiler results in a executable
which is a whopping ~75 % faster (in my test case that is).
To put in perspective: A ``VS7-C++ & /Ox'' compiled cvs-Ruby is
~ 10 % faster as an aggressively complied Cygwin cvs-Ruby.
~ 100 % faster as VS6-C++ compiled cvs-Ruby (with stock optimizations)
~ 150 % faster than the current Prag-Prog Ruby
