"Something is trying to run the c compiler"

["Mikhail T." <mi+thun%aldan.algebra.com@localhost>]

Hello!

I'm trying to build a package (devel/pkg-config in this case) and it 
fails complaining about C-compiler, that "can not create executables".

Looking into the config.log left after the failed configure-run, I see:

   configure:2924: checking for C compiler version
   configure:2931: gcc44 --version >&5
   PKGSRC-WARNING: Something is trying to run the c compiler,
   PKGSRC-WARNING: but it is not added to USE_LANGUAGES in the package
   Makefile.
   configure:2934: $? = 1
   configure:2941: gcc44 -v >&5
   PKGSRC-WARNING: Something is trying to run the c compiler,
   PKGSRC-WARNING: but it is not added to USE_LANGUAGES in the package
   Makefile.
   configure:2944: $? = 1
   configure:2951: gcc44 -V >&5
   PKGSRC-WARNING: Something is trying to run the c compiler,
   PKGSRC-WARNING: but it is not added to USE_LANGUAGES in the package
   Makefile.
   configure:2954: $? = 1

   conftest.c >&5

What's wrong? CC is set to gcc44 here, and CXX -- to g++44. The system 
is RHEL-5.4/amd64. Thanks!..
