Hi,

The gcc bundled with djgpp 2.03 seems to choke on the following inline
assembly statement :

long long clk_time;

__asm__("rdtsc":"=A"::"%eax","%edx");


The error message is :

Error : Can't find a register in class `AD_REGS' while reloading `asm'.

gcc --version returns 3.02

(Replacing "rdtsc" by ".byte 0x0f;.byte .0x31" doesn't help either.

The same program compiles correctly on my Linux (RH 6.2) box where the
gcc version returns egcs-2.91.66

Any ideas would be welcome.
