Revision: 1.36
Committed: 2004-11-14T23:24:51Z (19 years, 11 months ago) by gbeauche
Branch: MAIN
Changes since 1.35: +42 -2 lines
Log Message:
Check for egrep early, as AC_EGREP_CPP wouldn't work correctly otherwise
(e.g. GCC version not detected, likewise for ANSI C headers). Add check
for Windows exceptions support. Some cosmetics for Cygwin.
