Hi Scott,

yes please - the more test code the better.  I'm going to write some
test code which reads exactly 16k and pushes a char back and then
reads until eof and pushes a char back.

weird - could you possibly capture the C preprocessor output of
wraptime.c - you can do this by:


$ cd build-4.1.2/gcc
$ rm gm2/gm2-libs-iso/wraptime.o
$ make gm2/gm2-libs-iso/wraptime.o

 <...  lots of gcc command line info ...>

now cut and paste this command line and repeat it but critically
modify it by

replacing  '-c' by '-E'

and altering the destination output to say
 -o cppwraptime.build

if you can do the same for you private working compile of wraptime,
say use:
 -o cppwraptime.local

and email me these two files - hopefully I'll see enough differences.
Probably a configure issue..
