comparison compat.h @ 580:d7c338ac926a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Sweeping changes to the compatibility module, moved all socket code out of the DLL and into macros in compat.h, socksprintf() is now gone, replaced by the sockprint() macro and the vargs() function. This allows the DLL and application to be compiled with different compilers (and C libraries).
