Keil gcc uses uclibc, the version you require is:

int write (int file, char * ptr, int len)
{
    return len;
}
All the system functions are just non reentrant versions.

Be careful of uisng uclibc as a clib, even though it is a better lib 
for smaller devices it comes under lgpl rather than gpl. This is only 
really a problem if you are statically linking with the libs.
