annotate lwasm/lwasm.h @ 349:b62af915c2cc

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix includebin to use binary mode when emitting the contents of the file. For systems with the stupid distinction between binary and text files (I'm looking at you Windows), actually specify binary mode when reading the include file for a binary include. It worked fine on Linux and other Unix-like systems which treat files as a simple sequence of bytes but on Windows, you get the benefit of 0x1A causing an EOF signal with text mode files which is not helpful.
