Details:
The vpath directive is generally preferable to VPATH but it has one limitation
VPATH does not: there seems to be no way to query the current setting. We can
add to it with e.g. "vpath %.c path1 path2 ..." and clear the current setting
with "vpath %.c" but there's no way to find the "path1 path2" value. Since
path settings are accretive and cross include file boundaries and so on it can
be pretty challenging to figure out the current value in complex makefile
suites.
Unfortunately I have no suggestions for the syntax. It may be necessary to
drop this simply because there's no syntactical space for it. but I wanted to
put it in the record anyway.
