 Example (from v.centroids.py):

 {{{
 gscript.exec_command("v.category", type='area', **options)
 }}}


 fails with


 {{{

 }}}


 while modified source

 {{{
 gscript.exec_command("v.category.exe", type='area', **options)
 }}}
 works correctly.

 It seems like os.execvpe does not use PATHEXT environment variable (maybe
 because dot in filename overrides PATHEXT and ".category" is taken as file
 extension)
