 *
 * This library supports the USB on the STM32F4 and STM32F1
 * series of ARM Cortex Microcontrollers by ST Microelectronics.
 *
 * This file fixes the warnings of reentrant calls, due to modifications
 * since August 8th, 2022, on version 11.3 Rel1.
 * In this code, I do NOT use any functions of the standard library (NEWLIB).
 * Although these reentrant functions are not used, they started to be
 * requested by gcc, in NEWLIB requests, and, in their absence, generate
 * warnings of "not implemented and will always fail" on reentrant calls
 * close, lseek, read, kill and getpid.
