I'm trying to debug a gcc frontend (cobol for gcc) and get errors such as: ../../gcctrunk_with_cobol/gcc/cobol/cobcbei.c:462: error: invalid application of 'sizeof' to incomplete type 'struct lang_identifier' ../../gcctrunk_with_cobol/gcc/cobol/cobcbei.c:462: error: 'getdecls' undeclared here (not in a function) ../../gcctrunk_with_cobol/gcc/cobol/cobcbei.c:468: error: conflicting types for 'tree_code_type' which come from nested macros in gcc code. Is there an easy way (such as defining an environment variable in the build environment) to get the gcc build system to show the preprocessed code to help backtrack the problem? If not, any ideas to avoid laborious file-at-a-time handling? Thanks. -Tom
