Hello,

doc/automake.texi contains colon in @pxref, at line 879, @node VPATH Builds:

... these builds @pxref{General Search, , @code{VPATH}: Search Path for 
All Prerequisites, make, The GNU Make Manual}).

Please remove the colon, see the attachments for the motivation (texinfo 
documentation shall be extended to state that colons must be avoided in 
@pxref).

Със здраве
