[Rd] R compilation on old(ish) CentOS

[Ben Bolker]

   I probably don't want to go down this rabbit hole very far, but if 
anyone has any *quick* ideas ...

   Attempting to build R from scratch with a fresh SVN checkout on a 
somewhat out-of-date CentOS system (for which I don't have root access, 
although I can bug people if I care enough).

   ../r-devel/configure; make

ends with

gcc -std=gnu99 -I../../../r-devel/trunk/src/extra  -I. 
-I../../src/include -I../../../r-devel/trunk/src/include 
-I/usr/local/include -I../../../r-devel/trunk/src/nmath -DHAVE_CONFIG_H 
  -fopenmp  -g -O2  -c ../../../r-devel/trunk/src/main/connections.c -o 
connections.o
../../../r-devel/trunk/src/main/connections.c: In function ‘do_sockconn’:
../../../r-devel/trunk/src/main/connections.c:3477:5: error: too few 
arguments to function ‘R_newsock’
      con = R_newsock(host, port, server, serverfd, open, timeout);
      ^

serverfd, const char * const mode, int timeout, int options);
              ^
make[3]: *** [connections.o] Error 1

   Any suggestions for a quick fix/diagnosis?

   cheers
