<div>Remove the special static linking when PACKAGE_BUILDING is set.</div>
<div>When ezm3 is used, programs are always statically linked with the</div>
<div>Modula-3 libraries. This means that binaries built with this port</div>
<div>will be stand-alone, but still dynamically linked with the system</div>
<div>libraries. So, for example, they will work with runsocks</div>

<div><br />
</div>
<div>Building m3core.so, and therefore linking to it, is kinda the bothersome point.</div>
<div>I do realize the use cases though, say of multiple Modula-3 codebases, multiple Modula-3 .so</div>
<div>files, loaded into the same process, and sharing one m3core.so, one garbage collector.</div>
<div><br />
</div>
<div>That is something that might not work well w/o dynamic linking.</div>
<div>Though in the ELF model, it might..the first one kinda wins. But that doesn't</div>
<div>work on Mac with the two level namespace.</div>
<div><br />
</div>
<div>Perhaps delegating to libtool is a solution though, I have been mulling as well.</div>

Also, did you mean dynamic linking to Modula-3 i.e. m3core, or dynamically linked binaries in general, i.e. dynamically linked to libc?</div>
<div style="color:rgb( 0 , 0 , 0 );font-family:'calibri' , 'helvetica' , sans-serif;font-size:12pt">
These are really two separate things. Dynamic linking to libc is much more valuable and less negotiable and less problematic than dynamic linking to m3core. <span style="color:rgb( 0 , 0 , 0 );font-family:'calibri' , 'helvetica' , sans-serif;font-size:12pt">Some platforms
have no public stable syscall interface, except via thin layer in libc, so dynamic linking is required. e.g. Darwin and Solaris I believe, and NT. Libc versioning/compatbility is also generally pretty good.</span></div>
