Fix build with GCC 10. #94

Closed hvdijk closed 4 years ago

hvdijk commented 4 years ago

The variable tryglf is defined twice. With gcc -fcommon, the default up to GCC 9, the duplicate definition is silently accepted. With gcc -fno-common, the default as of GCC 10, the duplicate definition is rejected. Remove one of the definitions.
