[LinuxBIOS] FILO with the USB

[Fridel Fainshtein]

Etherboot does not work with gcc 4. At least filo part.
As I remember, I found a few strange things like
#if 0 <-- original
#define isdigit(c)      ((c & 0x04) != 0)
#define islower(c)      ((c & 0x02) != 0)
//#define isspace(c)    ((c & 0x20) != 0)
#define isupper(c)      ((c & 0x01) != 0)
#else <-- not optimized correction
#define isdigit(c)      (c >= '0' && c <= '9')
#define islower(c)      (c >= 'a' && c <= 'z')
#define isupper(c)      (c >= 'A' && c <= 'Z')
#endif

These strange things caused FILO in ETHERBOOT not to work.
I"ve never tested but does FILO in ETHERBOOT work if it is compiled with gcc 3?

Not optimized suggestion for allot2:
void *allot2(size_t size, unsigned int alignment)
{
       void         *addr;
       unsigned long addrval;
       int           pSize = sizeof(unsigned long);

   if(((alignment + 1) & alignment) != 0)
               return (void *)0;

       addr=malloc(size + alignment + /*2**/pSize);

       addrval=(unsigned long)addr/* + pSize*/;
       addrval+=alignment+1; //  0x12345600 + 0xff + 1
       addrval&=~alignment;  //  0x12345700
       *(unsigned long *)(addrval-sizeof(unsigned long))=addr;
       return (void *)addrval;
}

dma_to_td still appears, but "malloc_check: sizes mismatch" disappeared
and I can see a led blinking on my USB
