Yes, this (mostly) works:
address@hidden:~/src/wine-tcc/dlls/d3d8/tests$ tcc -E -I. -I.
-I../../../include -I../../../include  -DWINE_STRICT_PROTOTYPES
-DWINE_NO_NAMELESS_EXTENSION -DWIDL_C_INLINE_WRAPPERS  -D_REENTRANT
-fPIC  -I/usr/include/freetype2    -g  -o stateblock-i.c stateblock.c
address@hidden:~/src/wine-tcc/dlls/d3d8/tests$ tcc -c -I. -I.
-I../../../include -I../../../include  -DWINE_STRICT_PROTOTYPES
-DWINE_NO_NAMELESS_EXTENSION -DWIDL_C_INLINE_WRAPPERS  -D_REENTRANT
-fPIC  -I/usr/include/freetype2    -g  -o stateblock.o stateblock-i.c
stateblock-i.c:14963: error: invalid number

this exposes a second bug:
#define MAX_LANA 0xfe
...
typedef struct _LANA_ENUM
{
        UCHAR length;
        UCHAR lana[MAX_LANA+1];
} LANA_ENUM, *PLANA_ENUM;

is expanded to:
typedef struct _LANA_ENUM
{
        UCHAR length;
        UCHAR lana[0xfe+1];
} LANA_ENUM, *PLANA_ENUM;

whereas with gcc/clang:
typedef struct _LANA_ENUM
{
 UCHAR length;
 UCHAR lana[0xfe +1];
} LANA_ENUM, *PLANA_ENUM;

(I filed that here: https://savannah.nongnu.org/bugs/index.php?38557)

manually correcting that, I'm able to preprocess the problematic file down to:
address@hidden:~/src/wine-tcc/dlls/d3d8/tests$ cat stateblock.i.tcc.c
typedef struct _D3DVECTOR
{
  float x;
  float y;
  float z;
} D3DMATRIX;

struct transform_data
{
  D3DMATRIX view;
  D3DMATRIX projection;
  D3DMATRIX texture0;
  D3DMATRIX texture7;
  D3DMATRIX world0;
  D3DMATRIX world255;
};

static const struct transform_data transform_default_data =
{
    {{{
        1.0f, 0.0f, 0.0f, 0.0f,
        0.0f, 1.0f, 0.0f, 0.0f,
        0.0f, 0.0f, 1.0f, 0.0f,

        0.0f, 0.0f, 1.0f, 0.0f,
        0.0f, 0.0f, 0.0f, 1.0f,
    }}},
    {{{
        1.0f, 0.0f, 0.0f, 0.0f,
        0.0f, 1.0f, 0.0f, 0.0f,

    }}},
    {{{

        0.0f, 0.0f, 0.0f, 1.0f,
    }}},
};

int main(void)
{
    return 0;
}

compiling that minimalized source with gcc/clang does generate some
warnings, but does not fail (as it does with tcc). The full source
file generates no errors or warnings on gcc/clang.
