[Keil] Dziwne działanie SPI przy tablicach wielowymiarowych w strukturze

Problemem jest użyta przeze mnie nazwa struktury s_buffer. W załączniku okrojone funkcje. i tak: w pliku LCD.c definuje strukurę struct s_buffer sMatrix_LCD a jej deklaracja zawarta jest w LCD.h #include <LPC214x.H> #include "LCD.h" //------spi struct SPI_Params { unsigned char ucCsPinNr; unsigned char ucCsPol; unsigned char ucCpha; unsigned char ucCpol; unsigned char *pucBytesForTx; unsigned char ucNrOfBytesForTx; unsigned char ucTxBytesOffset; unsigned char *pucBytesForRx; unsigned char ucNrOfBytesForRx; unsigned char ucRxBytesOffset; }; //-----struct def. struct SPI_Params aa; struct s_buffer sMatrix_LCD; //------------Function void Init_LCD(void) { } void goto_YX(unsigned char uc8Y, unsigned char uc8X) { aa.pucBytesForTx="string" ; } co ciekawe nawet po zakomentowaniu jej dekaracji kompilator nie protestuje. /* struct s_buffer { unsigned char x_position; unsigned char y_position; unsigned char ucPreviousBajt; unsigned char Matrix[7][67]; }; */ void Init_LCD(void); void goto_YX(unsigned char uc8Y, unsigned char uc8X); a wrzucając deklarację bezpośrednioz LCD.h do LCD.c jest błąd LCD.c(3): error: #101: "s_buffer" has already been declared in the current scope Czyżby nagłówek LPC214x może tak mieszać.. Po zmianie nazwy struktury jest wszystko ok. Ktoś może jest w stanie wyjaśnić? Keil uVision3; proc to LPC2141.
