// [ HKLM\System\CurrentControlSet\Control\StorageDevicePolicies\WriteProtect: reg_dw: 1 ]
//
// NOTES:
// - This registry hack (KB555443) works only starting from XP SP2; I don't check for the SP.
// - If a drive is already attached, write enable seems to come in effect immediately;
//   Write disable becomes effective only after the drive is re-attached.

This is a preprocessor that converts C printf-like statements in C code to something like Linux bprintf and extracts format strings.
It can be used in small embedded systems to save memory and processing time on target.

The following describes our custom implementation for a 32-bit LE machine (Tensilica Xtensa CPU & xcc toolchain). One can tweak it as needed.

Limitations:
 * Limitation of the parser: ...... see in the py file
 * Limitation of codegen: ....... ditto. 
     Mainly, all arguments must be scalar.
     Format %s is supported only for constant strings (string literals, __func__ or __FUNCTION__)
