Compile error: ‘res’ undeclared (first use in this function)

[keithgg-carebit]

Hi, I'm unable to compile the library. I'm getting a compile error when using cmake.

.../pxlib/src/paradox.c:3870:25: error: ‘res’ undeclared (first use in this function)
 3870 |                 if(0 > (res = iconv(pxdoc->in_iconvcd, &iptr, &ilen, &optr, &olen))) {

I was able to fix it by declaring int res in that block.
