wchar.h: No such file

[Thimble Smith]

Hello.  I'm getting this error when trying to build the library:

Making all in src
gmake[2]: Entering directory `/usr/local/src/bld-libstdc++/src'
/bin/sh ../../libstdc++/mknumeric_limits `pwd`/.. ../../libstdc++
running mknumeric_limits
../../libstdc++/src/gen-num-limits.cc:44: wchar.h: No such file or directory
gen-num-limits failed to build, exiting.
gmake[2]: *** [../bits/std_limits.h] Error 1
gmake[2]: Leaving directory `/usr/local/src/bld-libstdc++/src'



That is using CVS sources I downloaded yesterday.  If I use the latest
snapshot, I have the same problem (wchar.h: No such file...), but it
happens a little bit later:

/bin/sh ../libtool --mode=compile pg++ -DHAVE_CONFIG_H -I. -I../../libstdc++-2.90.6/src -I.. -nostdinc++ -I../../libstdc++-2.90.6 -I../../libstdc++-2.90.6/stl -I../../libstdc++-2.90.6/libio     -g -D_GNU_SOURCE -fno-implicit-templates  -c ../../libstdc++-2.90.6/src/complex.cc

This is what I did:
  1) unpack the sources
  2) edit mk* scripts, changing g++ -> pg++ and
     /bin/bash -> /usr/local/bin/bash
  3) mkdir bld-libstdc++; cd bld-libstdc++
  4) CC=pgcc CXX=pg++ ../libstdc++/configure --prefix=/usr/tmp/libstdc++
  4) gmake

The only wchar.h I can find is in ../libstdc++/shadow/wchar.h.  I
have /usr/include/g++/std/cwchar.h (from g++ 2.7.2.3, I believe).  I'm
just not sure what the right way for me to fix my system is; has anyone
built the library on FreeBSD?

Thanks,

Tim
