"Bad magic number"

[Alec]

	Hi.

	Please, let me once again take advantage of your helpfullness.

	As a result of running Gmake under IRIX5.x on my application C-code 
        I receive the following error message:

Object file format error in: 
/Users1/lopresti/sergeyva/grass/src/libes/LIB.sgi5/libvect.a(line_struct.o):
Bad magic number 
*** Error code 1

	Could you tell me what could be the reasons that magic number is 
	so bad and how possibly could I fix this situation?

	Thankfully,
