[omniORB] Crash on omkdepend

Hi,

The binary omkdepend.exe crashes when it is compiled with visual studio in 64 bits.

The compilation gives the following warning:
pr.c(105) : warning C4047: 'initializing' : 'char *' differs in levels of indirection from 'int'

It's because the function TranslateFileNameD2U() is not declared. So, visual studio considers that this function is returning an int (instead of char*). The size of a pointer is 64 bits and the size of an int is 32 bits. At runtime, it gives a crash because it converts the pointer to an int and convert back to a pointer.

The following patch resolves the crash:
src/tool/omkdepend/pr.c:
/* $XConsortium: pr.c,v 1.17 94/04/17 20:10:38 gildea Exp $ */
