I've tried various combinations. I either get runtime errors relating to 
rb_str2ctr or just make errors.

1. $ perl -p -i.b -e 's/STR2CSTR/StringValuePtr/g' *.c
   $ make

form_wrap.c: In function ‘rbncurs_c_set_field_type’:
form_wrap.c:626: error: lvalue required as unary ‘&’ operand
form_wrap.c: In function ‘rbncurs_c_set_field_fore’:
form_wrap.c:698: warning: implicit conversion shortens 64-bit value into 
a 32-bit value
form_wrap.c: In function ‘rbncurs_c_set_field_back’:
form_wrap.c:712: warning: implicit conversion shortens 64-bit value into 
a 32-bit value
form_wrap.c: In function ‘make_arg’:
form_wrap.c:1134: warning: format not a string literal and no format 
arguments
make: *** [form_wrap.o] Error 1
