[flext] error while compiling parch PD

[Thomas Grill]

Hi,
if i remember correctly, compilation in shared mode under Windows  
requires linkage to flext-pd.dll, not to the static library.
I would also suggest to set FLEXT_SHARED and FLEXT_USE_CMEM macros  
with the compiler (or the Codeblocks environment) and not in the  
source code, since those settings must be uniform in a project (e.g.  
with multiple source files).
