Subject: [Rd] error compiling R-code

Hi,

I have been compiling R from source code with regularity (both R-patched
and R-devel) for several months now.  About two/three weeks ago I noticed a
compilation error in R-devel (see below).  I thought that the error will go
away in "due course" so I did not investigate it further.  Then I left on
vacation.

I just downloaded both versions of R sources (i.e., 2.2.0 patched and
2.3.0).  They both give me the same error, so my suspicion is that it is
just me having this problem.  Here is what I get:

...
gcc  -O2 -Wall -pedantic --std=gnu99 -DLEA_MALLOC -I../include
-DHAVE_CONFIG_H -DR_DLL_BUILD  -c arithmetic.c -o arithmetic.o
arithmetic.c: In function `do_math1':
arithmetic.c:886: error: `expm1' undeclared (first use in this function)
arithmetic.c:886: error: (Each undeclared identifier is reported only once
arithmetic.c:886: error: for each function it appears in.)
make[4]: *** [arithmetic.o] Error 1
make[3]: *** [rlibs] Error 2
make[2]: *** [../../bin/R.dll] Error 2
make[1]: *** [rbuild-no-mbcs] Error 2
make[1]: Leaving directory `/home/andyj/R-devel/src/gnuwin32'
make: *** [distribution] Error 2

I apologize if this was already asked.  I came back after about
week-an-a-half and I did not have time to go through hundreds of R
messages.  Hopefully this is something simple for somebody who is familiar
with the code.

I am on a Win2000 machine with all the necessary tools installed.  I have
not changed my setup in at least 2 months and, as I said above, I was able
to compile R with no problems until about 2/3 weeks ago, so perhaps I
missed some subtle change in the tools.

Thanks in advance,

Andy
