Hi, Attached is a fix for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57076 Currently, we cannot build GCC when the source directory contains a @ character (which is a problem for Homebrew, where we typically build in directories such as /tmp/gcc@10/src: https://github.com/Homebrew/brew/pull/9007) The problem is because gcc-vers.texi then contain an unquoted @ character, which is interpreted as a texinfo command. The patch fixes the rule in gcc/Makefile.in so that stray @ characters are quoted as @@
Tested and bootstrapped on x86_64-apple-darwin19
PS: It’s possible the same issue occurs with characters { and } in the path
(according to
https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Conventions.html).
Do you think they should be quoted too?
Cheers,
FX
