At some point in the past few weeks it became impossible to build trunk from a sparse checkout that omits certain directories.
Because I nearly always configure with --enable-languages=c,c++ I use git's core.sparseCheckout=true config or "svn update --set-depth" to avoid checking out the front-ends, libs and tests for java, fortran and ada. This has always worked fine until recently, when it resulted in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53832 /home/jwakely/src/gcc/gcc/cp/lex.c:559:41: error: macro "ggc_alloc_cleared_lang_decl" passed 1 arguments, but takes just 0 /home/jwakely/src/gcc/gcc/cp/lex.c: In function 'retrofit_lang_decl': /home/jwakely/src/gcc/gcc/cp/lex.c:559: error: 'ggc_alloc_cleared_lang_decl' undeclared (first use in this function) I know what I'm trying to do isn't supported, but if the contents of gcc/ada and gcc/fortran are required to build, shouldn't it be a hard error if they're missing, rather than generating an unusable gtype-desc.h file?
