Bug comments restored from Gmane.org:

I'm using wine cvs sources as of 20030115 and am running on a
linux-2.4/glibc-2.3 based system.

When I tried to configure wine recently, I was interested in having IPX
support.  However, configure was returning a negative result when it checked for
the necessary headers.  After confirming that both netipx/ipx.h and linux/ipx.h
were present, I examined the autoconf macro more closely.  It was then I
discovered that it was omitting a necessary header for IPX support on linux
systems:  sys/socket.h.  This is because the header is guarded by a test against
the existance of sys/socket.h.

The problem with the current wine configure.ac is that
AC_CHECK_HEADERS([sys/socket.h]) is placed *after* the check for IPX support. 
This is most unfortunate and will result in false negatives previously
described.

The solution is to place AC_CHECK_HEADERS([sys/socket.h]) right after
AC_CHECK_LIB(mmap,mmap).  This ensures that it will be properly defined in the
later test macros.
