* transition from plain Makefile to autotools, source files moved to src/
* configure.in: added test for x86 architecture
* src/voice.h: x86 specific asm optimization for double to int casts only

71     ## There are various ways to get dependency output from gcc. Here's

74     ## up in a subdir. Having to rename by hand is ugly.
75     ## (We might end up doing this anyway to support other compilers.)
76     ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
77     ## -MM, not -M (despite what the docs say).
78     ## - Using -M directly means running the compiler twice (even worse
79     ## than renaming).

96     ## This next piece of magic avoids the `deleted header file' problem.
97     ## The problem is that when a header file which appears in a .P file
98     ## is deleted, the dependency causes make to die (because there is
99     ## typically no way to rebuild the header). We avoid this by adding
