Subject: Use libiberty's lrealpath to avoid portability problems.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8451f4a52e71cf93d20313fb067efb14894d1cc9;p=gcc.git

Use libiberty's lrealpath to avoid portability problems.

The dmd front-end function FileName::canonicalName could be called
during the semantic pass of import("file") expressions, so still
requires that realpath() be redefined.

Initial patch by Rainer Orth.
