Hi all:
64-bit support for Portable Vector Format is not available at this
time. The fix that Markus cites below is to allow a 64-bit machine
to read/write in a native-sized vector format. It does not provide
compatibility. This was a fragment that I had left in the tree by
mistake -- I have a semi-functional 64-bit PVF library, but the code
is not compatible with 'lesser' machines at this point. I don't
expect to have this done for 5.0beta4 release.
I'll take this opportunity to mention that the PVF library is not
the only 32-bit component within GRASS. Over the past two years, I
have been correcting code that assumes 32-bittedness, but there is
still some there. New modules often are not 64-bit clean, so there
is an unending supply of code that needs attention.
When you are writing code, please remember that
sizeof(char *) == sizeof(int) only for the Intel platform (and a few
others...) If a function returns a pointer, you must not let it
default to an int type. This is the ANSI-C standard default for
implicitly declared functions. Prototypes are a Good Thing. 'lint'
is your friend.

The value of LNG_SIZ in portable.h was OK for 64-bits OS but not for
Linux/Intel. This prevented *many* vector programs to work (e.g.
d.vect).
