going down to strict -ansi c89 is quite overkill (no 'inline', and /* */-style comments). But with these fixes, the code compiles with the stringent flags: -Wextra -Wold-style-definition -Wmissing-prototypes -Wmissing-declarations and -Wdeclaration-after-statement Change-Id: I36222f8f505bcba3d9d1309ad98b5ccb04ec17e3

# This makefile is a simpler alternative to the autoconf-based build

# and 'dwebp' tools in the examples/ directory, along with the static

# library 'src/libwebp.a'.
