assimp: fail to compile in personal project

[RaanGi]

I have a project to test VitaGL and I use assimp to load the 3D meshes. With the update to assimp v5.3.1 the compilation breaks. It sais the there undefined reference to fseeko64, ftello64 and fseeko64. This is because in the new code there is no #else clause for the rest of cases in file ioapi.h.

I have been able to fix it with the next patch:

diff --git a/contrib/unzip/ioapi.h b/contrib/unzip/ioapi.h
index ae9ca7e83..50978316d 100644
--- a/contrib/unzip/ioapi.h
+++ b/contrib/unzip/ioapi.h

 #define ftello64 ftell
 #define fseeko64 fseek

-#if defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__)
+#if defined(__FreeBSD__) || defined(__OpenBSD__) || defined(__NetBSD__) || defined(__vita__)
 #define fopen64 fopen
 #define ftello64 ftello
 #define fseeko64 fseeko

I have used the above solution because is simpler.
