Subject: [PATCH] Revert "Fix logic error in macro file reader"
|
|
|
|
This trips over the following comment line in macros.python-srpm,
|
|
preventing all subsequent macros from loading:
|
|
|
|
Temporarily revert to let Python builds continue while looking for
|
|
proper fix.
|
|
|
|
This reverts commit 75275a87cff04da65d3557f2c40ea2b526528c4c.
