Fwd: GCC 4.8.1 MIPS

[Hendrik Greving]

Forwarding this to the mailing list as I have forgotten to reply-all.

Should anybody search for the same issue, my solution was to get the
right gawk version. gawk generates a optionslist and options.h file.
The GCC documentation states that gawk 3.1.5 is known to work. My
version was broken.

I have never gotten this problem.  It does look like gcc/options.h
was not created correctly.  It should be in your build directory
and contain things like:

#define MASK_MIPS16 (1 << 17)
#define TARGET_FLOAT64 ((target_flags & MASK_FLOAT64) != 0)
