Bug 2955. Workaround for lack of atomic operations in GCCE standard libraries (fall back to default use of Mutex)
A set of project files is available for WinCE. Get
libpng-1.2.5-project-wince.zip from a libpng distribution
site such as http://libpng.sourceforge.net
Put the zip file in this directory (projects) and then run
"unzip -a libpng-1.2.5-project-wince.zip"
