[xmlblaster] Solaris C build changes

["Joshi, Mehul" <joshim at omrsystems.com>]

FYI:

Just some notes in case someone else runs into the same issues compiling C
libs on solaris.
Please feel free to comment perhaps there are is a better way to do this...

OS:
SunOS fuj01 5.8 Generic_117350-05 sun4us sparc FJSV,GPUZC-M
$run command
$./build -verbose -Duse-CC=true  c
..this caused 2 errors in XmlBlasterUnmanaged.c file. They both seem to be
casting errors.
I have fixed these as follows:

============================================================================
===================
     75
    76  Dll_Export XmlBlasterAccessUnparsed
*getXmlBlasterAccessUnparsedUnmanaged(int argc, const char* const* argv){
    77     /** argv seems to be freed by C#, so we clone it here */
    78     int j,i=0;                   		 /* Changed line */
    79     char ** ptr; 
    80     j = sizeof(char *);			 /*New line*/
    81     ptr = (char **) malloc(argc * j);	 /* Changed line */
    82     for (i=0; i<argc; ++i) {
    83        ptr[i] = strcpyAlloc(argv[i]);
    84     }
    85     return getXmlBlasterAccessUnparsed(argc, ptr);
    86  }

   249     char *usage = (char

   250     return xmlBlasterAccessUnparsedUsage(usage);
   251  }
