I use newlib, it drives the RDCF2 FAT filesystem for the SD card, and 
newlib functions are used extensively throughout the code: memcpy, 
strncmp, etc.  I don't use newlib-lpc only out of how I write code, I 
would prefer to write my own extensions to a library so that I can 
quickly fix any problems later rather than spend time learning what 
someone else wrote.

Newlib is essentially a foundational library of common functions: 
memcpy, strcmp, strcpy, etc.  It also embodies higher level code such as 
printf, scanf, etc.  For myself, I use the file streams logic (fopen, 
fread, fputs) to implement a FAT 12/16 filesystem layer.  Rather than 
write my own stream code, it is more convenient to use what is already 
there.

Details on building a set of development tools is at:

newlib is also used with the LPC2106 processor on my board.
