When editing Makefile.am files, if/else constructs interfere with parsing logic. For example, all: hello.c if USE_GCC \tgcc hello.c else \tcc hello.c In this case, the outline should either show the gcc command or the cc command. In addition, in the processed Makefile.in files, the processed if statements (@cond@) are not being recognized as target rules. For example: all: hello.c @USE_GCC_TRUE@\tgcc hello.c @USE_GCC_FALSE@\tcc hello.c This causes the editor to not treat the two commands as commands for the all target.
Fixed in current repository. Automake if/else is evaluated and statements are either handled or ignored (currently conditions are defaulted to false). A patch also supports the Makefile.in processed statements so they are treated properly. There is no ignoring of Makefile.in statements and the prefixes are shown in the outline view.
