# SYNOPSIS |
|||
# |
|||
# AX_TLS([action-if-found], [action-if-not-found]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# Provides a test for the compiler support of thread local storage (TLS) |
|||
# extensions. Defines TLS if it is found. Currently knows about GCC/ICC |
|||
# and MSVC. I think SunPro uses the same as GCC, and Borland apparently |
|||
# supports either. |
