Ugh, man do I feel stupid. The ultimate source of the issue is this
line in config.h:
/* Define to the character that separates directories in PATH. */
#define PATH_SEPARATOR_CHAR ':'
As a result of this, vpath isn't parsing correctly. Is there a way to
have configure set PATH_SEPARATOR to ';' for a mingw32 host
irregardless of the shell used to run configure?
Sorry for wasting everybody's time.
