<h3>0.-Introduction</h3>
<p>The 1.5 beta 4 is the first available MSYS/MINGW build.<p>
<p>The only difference between the msvc build and the mingw build, is that the later one does not support the ms SEH exception handling. This is an important difference because some exceptions will not be catched and thus FB will abort, the sources using this exception handling are jrd/blob_filter.cpp, jrd/exe.cpp and jrd/fun.epp.</p>
<p>This port is maintained by Blas Rodriguez Somoza and Dmitry Sibiriakov.</p>

<h3>5.- USING BISON</h3>
<p>If you want to use bison to regenerate dsql/parse.cpp then you don't need to apply the patch included in 3 for make.shared.targets. To regenerate parse.cpp are only needed for developers who modify parse.cpp.<p>
<p>5.1.-Download bison-1.875.0-2003.02.10-1.exe from mingw site and install it.</p>
<p>5.2.-Patches to the build files</p>
<ul>
<li>In builds/posix/make.shared.target </li>
<ul>
<li>replace the following line<br><br>
<code>
sed -f $(SRC)/dsql/parse.sed &lt; $(SRC)/dsql/dsql.tab.c &gt; $@ <br><br>
</code>
with<br><br>
<code>
sed -e 's/\\r//g' $(SRC)/dsql/parse.sed > $(SRC)/dsql/parse2.sed<br>
sed -f $(SRC)/dsql/parse2.sed &lt; $(SRC)/dsql/dsql.tab.c &gt; $@ <br>
-rm $(SRC)/dsql/parse2.sed<br><br>
</code>
</li>
<li>This change is only needed to be sure the newline used is the unix one, sed will fail if the newline is the dos one.</li>
