Hi all,
I've got a little test program below. On Linux, it compiles
using:
gcc-3.4 -Wall -O3 -std=c99 lrintf_test.c -lm -o lrintf_test
and when run produces:
lrintf_test ( .00) : ok
lrint_test ( .00) : ok
lrintf_test (3.00) : ok
lrint_test (3.00

Linux uses glibc, Cygwin uses newlib. They're not the same thing.
Glibc is highly optimized and tweaked, newlib is designed as a small and
