Subject: Trouble rebuilding libc and friends
Precedence: bulk

I tried to rebuild the libc, and I encountered some problems. I thought I
should mention them, because IMHO these should not occur when rebuilding. I
am using DJLSR201.ZIP dated 10-31-96.

- In libm, the files src/libm/src/s_finite.S and sf_finit.S contain the line

setnel %al

The assembler (from Binutils 2.7) chokes on this, and IMHO rightly so, since
it seems to be saying "set if not equal: long" for an instruction that can
only take byte operands. The question is, though, should it be "setne %al"
(set al if not equal), or "setnle %al" (set al if not less than or equal)?

- In src/mkdoc/makefile, the linker invocation fails to include libgcc after
libc, causing an "undefined reference". This is easily fixed by adding it,
or by changing the complicated linker line to "gcc -o ../../bin/mkdoc.exe
mkdoc.o".

Any input welcome.
