Hija,

just curious, is it expected that configuration of a GIMP
build will fail if configure cannot find a C++ compiler?

...
checking for dlfcn.h... yes
checking for g++... no
checking for c++... no
checking for gpp... no
checking for aCC... no
checking for CC... no
checking for cxx... no
checking for cc++... no
checking for cl... no
checking for FCC... no
checking for KCC... no
checking for RCC... no
checking for xlC_r... no
checking for xlC... no
checking whether we are using the GNU C++ compiler... no
checking whether g++ accepts -g... no
checking dependency style of g++... none
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

By supplying a C++ compiler via CXX env variable it happily
passes that point:
...
checking for dlfcn.h... yes
checking whether we are using the GNU C++ compiler... yes
checking whether g++-3.4 accepts -g... yes
checking dependency style of g++-3.4... gcc3
checking how to run the C++ preprocessor... g++-3.4 -E
checking for g77... no
...

config.log unfortunately doesn't tell anything sensible...

Servus,
      Daniel
