If you try to assign and export on the same line on some older /bin/sh implementations, it complains: ``` $ export "NAME=value" NAME=value: is not an identifier ``` Also, as written, the name and value are quoted together. This also makes old /bin/sh sad: ``` $ "NAME=value" NAME=value: not found ``` This commit rewrites run-compiler's assignments and exports to work with old /bin/sh, splitting assignment and export into two separate statements, and only quote the value. So now we have: ``` NAME="value" export NAME ``` While we're here, make the same change to the two supporting assign+export lines preceeding the script to be consistent with how exports work throughout the rest of configure.ac.

Splitting assignments and export into multiple commands to make the script work in older systems with an sh interpreters that doesn't comply with POSIX issue 6 or issue 7 is fine. 👍
That makes any sh sad, not only old sh. :( |

Fair enough, we can rewrite the commit message to drop that note if we like. |
