narrowing error - where can I configure [-Wnarrowing]

ERROR FIXED - NEW ERROR - structured binding declaration.

I have the following array:

uint16_t pat8[] = { 32,32,16, // width,height,bits 0x1840,0x38c0,0x4100,0x4940,0x4940,0x5161,0x4961,0x2060,0x1860,0x4960,0x4940,0x4940,0x4940,0x4920,0x4940,0x4941, 0x2060,0x4100,0x4920,0x4940,0x4940,0x4940,0x4120,0x1840,0x4960,0x59a1,0x5161,0x4940,0x4940,0x4100,0x4120,0x38e0, 0x5181,0x1020,0x38e0,0x4960,0x5181,0x4961,0x2060,0x4120,0x4120,0x1860,0x5160,0x4940,0x4940,0x4940,0x4920,0x4940, 0x5161,0x2060,0x4100,0x4940,0x4940,0x4940,0x2080,0x4940,0x2080,0x5181,0x59a1,0x5181,0x4960,0x4940,0x4100,0x38e0,

And I get the error:
pat2.h:14:14: error: structured binding declaration cannot have type 'uint16_t' {aka 'short unsigned int'} 14 | uint16_t pat2[] = { | ^~ pat2.h:14:14: note: type must be cv-qualified 'auto' or reference to cv-qualified 'auto' pat2.h:14:14: error: empty structured binding declaration

Then I have:
if(bgMode==0) backgroundPattern(t, pat2);
Gives the error:
gfx3d.h:470:44: error: expected primary-expression before ')' token
470 | if(bgMode==0) backgroundPattern(t, pat2);

Called Function:
void backgroundPattern(int32_t i, uint16_t *pat) { int32_t x,y,xp,yp; xp = 25*fastSin(4*i)/256+50; // 256 not MAXSIN=255 to avoid jumping at max sin value yp = 25*fastSin(5*i)/256+50+yFr; for(y=0;y<NLINES;y++) for(x=0;x<WD_3D;x++) frBuf[SCR_WD*y+x] = pat[((y+yp)&0x1f)*32 + ((x+xp)&0x1f)]; }

Unfortunately from this description I cannot see, what is causing the error(s). You can specify additional compiler options in your Makefile before the include ../Rules.mk statement like that:

CFLAGS += -Wnarrowing
