gcc48 +universal build fails on OS X Sierra

[ibethune (Iain Bethune)]

Hi, doing a clean install of my ports after upgrading to Sierra, I ran into the following (minor) problem with gcc48:

Iains-MacBook-Pro:src ibethune$ sudo port install gcc48 +universal
--->  Computing dependencies for gcc48
--->  Building gcc48
Error: org.macports.build for port gcc48 returned: command execution failed
Please see the log file for port gcc48 for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc48/gcc48/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port gcc48 failed

The specific cause of the bug is the file - /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc48/gcc48/work/gcc-4.8.5/gcc/doc/gcc.texi

The build process cannot deal with the @tex ... @end tex on lines 88 and 90. I applied manually the fix described here: ​https://gcc.gnu.org/ml/gcc-patches/2013-09/msg02100.html i.e. replacing the @tex .. @end tex with @email{...} and the build proceeded normally.

Will do, I don't think I am able to change this after submission, right? Sorry!

That is unfortunately correct.

More versions of gcc are affected and need to be fixed. See #53076.
