<br><font size=3>Hi!</font>
<br>
<br><font size=3>After Paul Hiemstra gave me the hint to make a fresh install
of MinGW,</font>
<br><font size=3>I managed to build the Proj-4 library libproj.a on my
Win-XP box.</font>
<br><font size=3>Then I encountered problems with the gfortran version
included with that gcc collection,</font>
<br><font size=3>and someone pointed me at an ultimately fresh gcc snapshot,
which </font>
<br><font size=3>can be downloaded from www.equation.com. </font>
<br><font size=3>My fortran performance was greatly boosted by this upgrade,</font>
<br><font size=3>but Proj-4 now refuses to be built. Again... Of course
I still have the</font>
<br><font size=3>old library from the gcc version that I installed some
days ago, but I don't like</font>
<br><font size=3>having to have two gcc versions for all the different
needs.</font>
<br>
<br><font size=3>The gcc version that builds Proj-4 without problems is:</font>
<br>
<br><font size=3>$ gcc -v <br>

<p><font size=3>Somehow the new gcc version cannot compile the same code
that went <br>
allright with the old version, and that had led to a working C sample.
<br>
Is the Proj-4 project "very sensitive" or "less generic"?
Or is there a bug in the gcc snapshot? </font>
