[Proj] undefined cache functions

[Matthias Schneider]

Hi,

when I try to build the proj4 4.7.0 with Visual Studio 2005 I got some 
warnings which I have to solve:

********************
1>.\src\proj-4.7.0\src\pj_init.c(119) : warning C4013: 
'pj_search_initcache' undefined; Assumption: extern with return type int
********************

There are several problems related to "pj_insert_initcache", 
"pj_acquire_lock" and "pj_release_lock".

Is there a solution for that problem? I found nothing so far. With 4.6.1 
everything runs fine :(

Regards,
Matthias
