Subject: Correct slight logic error in processing IF in build.info
X-Git-Tag: OpenSSL_1_1_0-pre4~107
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c5798e0eb557cf13852a3982429a641d5c88bcbe;p=oweals%2Fopenssl.git

Correct slight logic error in processing IF in build.info

This corrects a fault where the inner IF in this example was still
being acted upon:

  IF[0]
    ...whatever...
    IF[1]
      ...whatever more...
    ENDIF
  ENDIF

With this change, the inner IF is skipped over.
