Yes. From `C-h v compilation-error-regexp-alist RET':

Alist that specifies how to match errors in compiler output.
Each elt has the form (REGEXP FILE-IDX LINE-IDX [COLUMN-IDX FILE-FORMAT...])
If REGEXP matches, the FILE-IDX'th subexpression gives the file name, and
the LINE-IDX'th subexpression gives the line number.  If COLUMN-IDX is
given, the COLUMN-IDX'th subexpression gives the column number on that line.
If any FILE-FORMAT is given, each is a format string to produce a file name to
try; %s in the string is replaced by the text matching the FILE-IDX'th
subexpression.
