Doxymacs has only one single .c file. In the file, it has inline functions defined as follows, without any other declaration: inline void foo (void) { // body } It might be intended to be inlined at the call sites. There are about 12 inline functions declared and defined in such a way. It worked probably with the default inline-related options in gcc 6.4 or lower. However, it does not work with the default inline-related options with gcc 7. The problem seems that gcc 7+ may not generate the function's body in assembly while it may use 'call' instructions at some of the call sites. Thus, in my gentoo AMD64 machine, gcc 7.2 failed to build the package due to the linking time error: "undefined reference to." I guess, all 'inline' should be replaced with 'static inline' as there is only a single .c file here. Or, the compilation option -fgnu89-inline needs to be added as a walkaround.
Can you provide a patch?

Created attachment 500966 [details, diff] patch to /var/tmp/portage/app-emacs/doxymacs-1.8.0-r3/work/doxymacs-1.8.0 Add static inline function declaration would work for both gcc 5.4 (stable) and 7.2 (masked with '**')
I have just added a patch that I would suggest. I am new to open source bugzilla systems & conventions. I just made my account to report this bug, hoping emerge could build doxymacs at some point in the near future although I use newer gcc such as 7.2 or even upstream. I am not sure if I am following the coding standard, appropriate way of communication, etc. If not, please, kindly let me know. Thank you!
